CO2 Laser Tubes long lasting good quality 40W 60W 80W 100W 120W150W The Shanghai Puri 60W-100W small&medium power CO2 laser tube mainly used for laser engraving and cutting, applies to the vast majority of domestic the laser machinery manufacturing. Puri laser tube with middle & small power is excellent in good laser spot mode, enough power, long life, etc...Laser Tube Working Principle: High-pressure discharge stimulate high concentration CO2 to generate laser. Laser Tube Laser Wave Length: 10.6um. Laser Tube Laser Mode: Low order mode. Laser Tube Water-Cooling: Purified water, appropriate temperature 10-35C. Laser Tube Working Environment: Temperature 5-35C, humidity 10-60%, clean environment, no serious pollution. Laser Tube Working Current: 16~22mA is appropriate (excessive current will affect laser power and laser tube lifetime. Laser Tube Safety Demand: CO2 laser tube outputs invisible light, positive with high pressure, if necessary, eyewear is essential. Laser Tube Laser State: Laser power will be attenuated when the laser tube is used at a certain time; If the laser is pink, it is in normal condition; If the laser is white, it means the laser power is attenuate. ( Laser tube is consumable, please change a new one when it can't meet demand due to attenuation. ) Laser Tube Laser State: 1, There are two points to support the laser tube at two sides, when you install the laser tube, the two points should be in 1/4 of the laser tube; 2, On the basis of cooling water above-in and below-out, if you rotate the laser tube slightly, it will affect laser spot and laser power.
