The real magic of a fractional CO2 laser treatment takes place in the months following the procedure. [11][12][13][14] CO2 lasers can be used in place of a scalpel for most procedures, and are even used in places a scalpel would not be used, in delicate areas where mechanical trauma could damage the surgical site. The CO2 laser has the longest wavelength of all the lasers on the market and can be used safely on darker skin types with appropriate adjustments in the settings. AMADA's 3kW ENSIS fiber laser technology utilizes a highly innovative resonator to automatically and precisel⦠Power (%): 30-40 (For 40 watt laser) Speed (mm/s): 300 ; Interval (mm): 0.4 (This interval allows you to distinguish between engraved lines) Engrave the image. How can I quickly and easily determine the optimal laser parameters for my material? Lower frequency and higher ⦠And finally, from the "100W Co2 Laser Tube Operation Instruction": It is not proposed to control laser power with high-frequency modulation, because it will have impact on the service life of the laser. The active laser medium (laser gain/amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied. This varies from material to material and is also dependent on the specific settings of the laser. Usually, for a CO2 laser, the value can be set within a rough range of 1,000 to 60,000 Hz. Marking area up to 44.1 x 25.0 inch. If the engraving area is small, the laser may not have sufficient distance to get up to the full speed, so you may need to reduce the power slightly if you want a shallower engraving on small jobs. RF CO2 | 350-550-750-850 W | 10.6 µm | Self-Refilling Blade RF Self-Refilling (350W - 850W) El.En. At the same speed and power settings, any rise in the frequency ends up with a reduction in the channel size. Because the laser transitions are actually on vibration-rotation bands of a linear triatomic molecule, the rotational structure of the P and R bands can be selected by a tuning element in the laser cavity. Using nitrogen or argon gas as cutting gas ⦠A "high" cutting speed is 10%. It specifies the number of laser pulses per second. While other materials can be extremely hazardous to either humans or the machine itself (like PVC and ABS). Otherwise, go to next step fot settings. [4] It is also very easy to actively Q-switch a CO2 laser by means of a rotating mirror or an electro-optic switch, giving rise to Q-switched peak powers of up to gigawatts (GW).[5]. Ahigher chosen speed (e.g. Just wondering if anyone has a suggestion for what my laser frequency or settings should be for this material. I do understand differences in lasing process (somewhat) by now⦠3 months digging in the âbooksâ waiting for my machine to arrive⦠Such "line-tuneable" carbon dioxide lasers[6] are principally of interest in research applications. Login. When the laser cutter is working, it doesn't leave the laser on for the duration of the cut. Amplification. That means it will only output 50 watts over a period of time. Fusion cutting is another standard process used in metal cutting, and it can also be used to cut other fusible materials, such as ceramics.. A great example of this technology used on a white MacBook is on the following link to the Epilog's website. 1. The type of laser being used is the primary consideration and the settings between a solid state laser and a CO2 will be entirely different. CO2 lasers are used in spectroscopy[17] and the Silex process to enrich uranium. Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. In this example, settings around 100% power and 30-60% speed should be optimal. The more power, the darker and deeper your engravings will be and the ⦠Laser cutting is a popular manufacturing process utilized to cut various types of materials economically. Here is short video that shows you. We recommend a minimum of 30W of power for CO2 lasers, and 10W of power for solid state lasers. Please visit http://www.DIY3DTech.com for more information on this and many other projects! The CO2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.6 and 10.6 micrometers (μm). Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser.The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. - 191 - APPENDIX B: MATERIAL SETTINGS Fusion Series Suggested Material Settings (CO2) • These are only suggestions: Every type of material will react differently with the laser, even from one plastic to the next. See reference table for details. The high voltage laser power supply settings can greatly affect the lifetime of the CO2 glass laser tube. Frequency (Hz, PPI): The frequency parameter specifies the number of laser pulses per second. 100% is maximum power. 25 or 30 watts, and are having trouble marking certain substrates, here is another tip. Some of the main influencing factors of a good laser cut are listed below. Epilog Laser Cutters. However, there are also applications in which deliberate defocusing is desired. Irrelevant to me, hence filtered out. For example, if you want to achieve a smooth edge when cutting acrylic, you need higher temperatures and thus this value is set to at least 5,000 to 20,000 Hz. Sheet made from Eastman Spectar™ copolyester can be laser cut. Because the atmosphere is quite transparent to infrared light, CO2 lasers are also used for military rangefinding using LIDAR techniques. These lasers are primarily used for metal cutting, though you will see CO2 laser energy as low as 150 watts for cutting thin metals. The following are suggested laser cutter configuration settings for various materials. Test Your Material to Determine Laser Speed and Power Settings: In this Instructable we will use a test file to find out how the laser works with your material when it is cutting and engraving at different speed and power settings. The frequency of the laser affects the channel size. Laser cutting and marking is a skill you must develop. closer to the material) up to 127 mm (table moves down, i.e. The population inversion in the laser is achieved by the following sequence: electron impact excites the {v1(1)} quantum vibrational modes of nitrogen. Power is how powerfully the laser fires regardless of speed. The z-offset describes the focus setting. Also available is a laser cutter user guide.. From #34 (comment).. Add a '$' setting to allow different laser PWM frequencies. In marking metal and plastic,There is a setting parameter range for reference to test ,Speed 100-2000 adjustable,Power 30-80 adjustable,Frequency 5-30. Lower CO2 wattage will have an effect on metal similar to the light from a flashlight bouncing off of a mirror. Fractional CO2 lasers excel at treating deeper wrinkles, more severe textural changes from sun damage, wrinkles, blotchiness, acne scars, and surgical ⦠Override PPI Only available on Trocen controllers, the PPI setting (Pulses Per Inch) lets you tell the laser to send an exact number of pulses per inch of travel, instead ⦠Because of the high power levels available (combined with reasonable cost for the laser), CO2 lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. For example, this approach is appropriate for a relief engraving. The power and speed laser parameters are the most important settings in the material database. In marking metal and plastic,There is a setting parameter range for reference to test ,Speed 100-2000 adjustable,Power 30-80 adjustable,Frequency 5-30. YES! With the exception of the Zing Starter Series, which goes up to 1000 DPI, the rest of Epilog's product line can engrave at resolutions up to 1200 DPI. [8] CO2 lasers may be used to treat certain skin conditions such as hirsuties papillaris genitalis by removing bumps or podules. Frequency: 1% Focus: .05” The contrast / brightness of marks achievable on the fiber laser are excellent and can often be much brighter than marks from a C02 laser. Speed 4. For example, large-scale engravings of TroLase materials are engraved at high speeds between 80 and 100%, but for photo engravings with lots of detail on wood, the speed should not exceed 10%. The four most important settings of a laser cutter are power, speed, frequency and for focus distance. With our CO2 laser engravers and laser cutters, you can cut and engrave on wood, fabric, acrylic. Lenses and Focus 3. This specifies the number of laser pulses per second. Lasers were first used for cutting in the 1970s. 100%) and lower frequency (e.g. Applications include gynecology, dentistry, oral and maxillofacial surgery, and many others. Frequency depends completely on the material used. There are a whole host of materials that a CO2 laser cutter can cut, etch or mark â but some â due to the material surface reflection â just wonât work (aluminum is an example). Override PPI Only available on Trocen controllers, the PPI setting (Pulses Per Inch) lets you tell the laser to send an exact number of pulses per inch of travel, instead of varying the beam power directly. This means that the laser source is not pulsing quickly enough to mark a continuous line. Because nitrogen is a homonuclear molecule, it cannot lose this energy by photon emission, and its excited vibrational modes are therefore metastable and relatively long-lived. I recently bought a 50W laser cutter and have been struggling to cut through 1/4inch plywood. 3 - Frequency vs Hatch Grid 4 - Setup Squares for Distortion (PDF) 5 - EzCad Manual (PDF) If you want to contribute to this site, please add your fiber laser settings. It remains to be seen if it is as effective as the traditional CO2. These instructions show a sub-$100 laser power meter probe at work, taking quick laser power measuremen… It was invented by Kumar Patel of Bell Labs in 1964,[1] and is still one of the most useful. 's Blade RF Self Refilling is not only a radio frequency CO2 laser source, engineered for mid-power applications on plastic, wood, leather and other materials.It's engineered … Frequency 3. A laserâs wattage, the type of optics, the quality of the beam, the spot size, and even the software used will affect the mark quality you will achieve with a given power setting. It specifies the number of laser pulses per second. Power settings that are too high can melt and distort many materials. I am confident its not an alignment or laser tube problem. Frequency: 1% Focus: +.06 to +07 The contrast / brightness of marks achievable on the fiber laser are excellent and can often be much brighter than marks from a C02 laser. In terms of wavelength, CO2 lasers produce infrared light (9.4 to 10.6 micrometers), you won’t be able to see the beam while it is running. Minimum Watts required for Fiber or CO2 Laser Our products are a perfect solution to mark on a variety of different substrates with a CO2 or Fiber laser/Yag laser. This is the frequency of light t he laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Fast speeds lead to short exposure times, slow speeds lead to long exposure times. For high power applications, gold mirrors and zinc selenide windows and lenses are preferred. Login or register to add settings . Laser wavelength can be tuned by altering the isotopic ratio of the carbon and oxygen atoms comprising the CO2 molecules in the discharge tube. further away from the material). Note that cutting and engraving speeds are not comparable. The Power laser parameter describes the output power of the laser. The Lumenis CO 2 laser solutions are uniquely designed to provide diverse treatment options in the operating room or the outpatient setting, under local or complete anesthesia. There is no point in setting a PWM pulse duration less than the lasers ability to respond! CO2 lasers can be used to remove vocal fold lesions,[9] such as vocal fold cysts. With some materials, for example, it can be advantageous to engrave with lower power and high speed, and then repeat this process several times. Frequency depends completely on the material used. Because CO2 lasers operate in the infrared, special materials are necessary for their construction. The increase in collagen production and the creation of new skin cells in the channels significantly reduces the appearance of dark spots caused by melasma. All settings noted use the default resolution which is 500 or 600, depending on the make of your laser system. Some examples of medical uses are laser surgery and skin resurfacing ("laser facelifts", which essentially consist of vaporizing the skin to promote collagen formation). Full Spectrum Laser 6216 S Sandhill Rd Las Vegas, NV 89120 702-802-3100 While the material was inexpensive, the lenses and windows degraded slowly with exposure to atmospheric moisture. Less time = less cost. All settings noted use the default resolution which is 500 or 600, depending on the make of your laser system. Taking the fiber laser out of focus by +.03” - .09” broadens the beam and produces a very bright mark on anodized coating. Sadly the wavelength from CO2 Lasers make it really difficult and almost impossible to engrave on polycarbonate. Furthermore, Air Assist protects the lens from damage, as it stops dust from adhering to it in the first place. Guide. Epilog's high-speed CO2 laser machines come in a variety of configuations to fit your budget and application processing needs. For example, if you want to achieve a smooth edge when cutting acrylic, you need higher temperatures and thus this value is set to at least 5,000 to 20,000 Hz. How to Test and Set a Chinese (China) Made CO2 Laser Power Supply to Get Long Life From Your CO2 Laser Tube for Your Laser Engraving and Laser Cutting Machine System: Be safe when performing this project. Carbon dioxide lasers have become useful in surgical procedures because water (which makes up most biological tissue) absorbs this frequency of light very well. AMADA engineered the 3kW ENSIS 3015 RI to include an innovative Rotary Index with the power and speed to efficiently transition from flat sheet to tube or pipe cutting. My info comes mostly from chinese CO2 gas laser users, diy laser builders, K40 users etc. If you have other settings youâd like to suggest, please send an email to design_help@ncsu.edu with the details. Will likely implement this as value with the current $32 laser mode setting, such that 1, 2, or 3 would indicate different frequencies.. Feel free to consult our "Choosing a Laser section for more information". Gas 5. The Q-switch is an electro-optical system, which controls the opacity of a lens making it possible to change the laser beam frequency. The finest frequency selection may also be obtained through the use of an etalon. The active laser medium (laser gain/amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied. A guide for engraving speeds is between 500-600mm/sec for DC lasers. In flow-through lasers, a continuous stream of CO2 and nitrogen is excited by the plasma discharge and the hot gas mixture is exhausted from the resonator by pumps. Let's say you have a 50 watt CO2 laser. 994614 Marchtrenk, Austria. Incorporating fiber laser cutting technology helps users process a variety of tubing and pipe with greater speeds compared to a CO2 system. When engraving TroLase engraving materials, for example, a more attractive engraving result is achieved without Air Assist. Optimal laser parameters for laser engraving and laser cutting for CO2 laser applications. Therefore, for [â¦] Laser Source: CO2 laser, 30-120 watts; Work Area: 16" x 12" (406 x 305 mm) up to 40" x 28" (1016 x 711 mm) Max. Material Height: 4.5" (114 mm) up to 13.25" (336 mm) Materials compatible with a CO2 laser ⦠I have a Full Spectrum Laser 12x20 Hobby Series CO2 45 watt. If you are using a lower power laser, i.e. The first frequency measurement in the 10 m region was reported by Daneu et al. Speed is how quickly or slowly the laser nozzle will move around in the X and Y directions. Having less variables will help to find the optimum settings faster. Advantages include less bleeding, shorter surgery time, less risk of infection, and less post-op swelling. In the next few years, the application of laser cutting in precision machining and micro-machining will also gain substantial growth. Epilog's high-speed CO2 laser machines come in a variety of configuations to fit your budget and application processing needs. This observation is clear in Fig. This parameter is used to adjust the laser output frequency by directly operating the Q-switch. Both materials present the same feature with regard to frequency. In practice, together with isotopic substitution, this means that a continuous comb of frequencies separated by around 1 cm−1 (30 GHz) can be used that extend from 880 to 1090 cm−1. [3], The CO2 laser can be constructed to have continuous wave (CW) powers between milliwatts (mW) and hundreds of kilowatts (kW). Several Mark Setting Objects may be used in a marking sequence especially if marking Single Line and True Type fonts with Shape or Vector Drawing objects in the same layout each type of marking object generally needs different laser settings to get the best performance. Use these settings as your starting point then adjust one variable at a time until you achieve the result you desire. I dismiss any info i find on fiber or RF lasers. Material Height: 4.5" … We have summarized some tips & tricks for you. There are also diamond windows and lenses in use. Melt Cutting. Power 2. Recommended Power Settings for Material Test. Here is a brief explanation. For dark wood engravings or stamp engravings, you generally need high power, whereas low values are used for materials such as paper. Obviously the faster it moves, the less time it will take for your project to complete. 20 kHz) cause a “perforation." The 9–12 μm wavelength of CO2 lasers is useful because it falls into an important window for atmospheric transmission (up to 80% atmospheric transmission at this wavelength), and because many natural and synthetic materials have strong characteristic absorption in this range.[2]. I've recently installed a G Weike LC1390 machine with a 130/150W Reci W6. Choose settings that give a durable mark without overpowering or damaging the object. The table below shows the output range for nine possible isotope combinations:[2]. The only solution (so far) to engrave this material is to use a YAG/Fiber laser. [citation needed] The specific proportions vary according to the particular laser. Laser Source: CO2 laser, 30-120 watts; Work Area: 16" x 12" (406 x 305 mm) up to 40" x 28" (1016 x 711 mm) Max. By rotating the diffraction grating, a particular rotational line of the vibrational transition can be selected. The CO2 laser at the 9.25–9.6 μm wavelength is sometimes used in dentistry for hard-tissue ablation. Midrange values are use to reduce over burn when cutting, and high values are often used when more heat is desired to melt the sides when cutting acrylic. The example below explains the relationship between frequency and speed. PWM frequency: The inverse of PwmPeriod is the PWM frequency. ABS Emits cyanide gas and tends to melt ABS does not cut well in a laser cutter. CO2 lasers are the best suited for soft tissue procedures in human and animal specialties, as compared to other laser wavelengths. Sadly the wavelength from CO2 Lasers make it really difficult and almost impossible to engrave on polycarbonate. The filling gas within the discharge tube consists of around 10â20% carbon dioxide (CO 2), around 10â20% nitrogen (N 2), a few percent hydrogen (H 2) and/or xenon (Xe) ⦠The width of laser cut or kerf, quality of the cut edges and the operating cost are affected by laser power, cutting speed, assist gas pressure, nozzle diameter and focus point position as well as the work-piece material. The Speed laser parameter describes the movement of the laser head. Polycarbonate is a poor choice for laser cutting. The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. Basically, cutting is slower than engraving. For a CO 2 laser, the value can be set within a range of 1,000 to 60,000 Hz. [2] who related the frequencies of R(10) and R(12) lines of the 0001 - 0200 band of C02 to the frequency of the 28 4m water vapor laser line. Have you ever wondered what that frequency setting does on your laser? Find out more about laser cutting at www.LaserXYZ.com. However, there are applications in which the Air Assist is deliberately switched off. IF YOU DO IT WRONG THEN YOU CAN BE ELECTROCUTED. We'll do this before we run our main project file so that we can optimize for the… In this case, the lens must be checked for contamination more frequently than with Air Assist. Prisms are not practical as tuning elements because most media that transmit in the mid-infrared absorb or scatter some of the light, so the frequency tuning element is almost always a diffraction grating. The carbon dioxide molecules then transition to their {v20(0)} vibrational mode ground state from {v1(1)} or {v20(2)} by collision with cold helium atoms, thus maintaining population inversion. Depends on different materials and the marking effects you want so for a new operator may need conduct dozens of trials to know the ideal marking parameters for each material and even some experienced engineers […] Studies have shown that compared with other types of lasers and treatment modalities, Physicians using CO 2 lasers for ear surgery can attain superior outcomes (1,2,3).. When using CerMark Metal Marking Solution , remember that not all metals use the same speed setting. In sealed lasers, this takes place as the helium atoms strike the walls of the laser discharge tube. In modern industrial production, laser cutting is more widely used in sheet metal, plastics, glass, ceramics, semiconductors and materials such as textiles, wood and paper. The PPI parameter (=pulses per inch) determines how many laser pulses per inch are used for the engraving. Hey Folks, I'm a long time lurker but haven't posted much here. Brand of Acrylic 2. For example, when engraving large areas on TroLase, we recommend defocusing 2mm for a consistent engraving result. What do these parameters such as power, speed, ppi, Hz, pass, Air Assist, z-offset actually mean? The 10.6 μm CO2 laser remains the best surgical laser for the soft tissue where both cutting and hemostasis are achieved photo-thermally (radiantly). Typically, the mirrors are silvered, while windows and lenses are made of either germanium or zinc selenide. Setting the frequency at a low value (50 to 100) will produce a perforation. During laser engraving and laser cutting, the supply of compressed air can significantly influence and improve results. Settings are 100% Speed, 50% Power, 150Hz Frequency. Type of Acrylic 3. Typical laser cutting settings for acrylic require higher power (watts), higher frequency (pulses per sec), and less air assist compared to Spectar of similar thickness. The most basic form of a CO2 laser consists of a gas discharge (with a mix close to that specified above) with a total reflector at one end, and an output coupler (a partially reflecting mirror) at the output end. N2{v1(1)} and CO2{v3(1)} being nearly perfectly resonant (total molecular energy differential is within 3 cm−1 when accounting for N2 anharmonicity, centrifugal distortion and vibro-rotational interaction, which is more than made up for by the Maxwell speed distribution of translational-mode energy), N2 collisionally de-excites by transferring its vibrational mode energy to the CO2 molecule, causing the carbon dioxide to excite to its {v3(1)} (asymmetric stretch) vibrational mode quantum state. This setting also affects the quality of the laser cut. Table Setup 2. This means that the material is less stressed per pass.
