1. Promised Quality 
2. Good Light Spot 
3. Long Life
4. Power:25W-300W

The Shanghai Puri 120W-160W 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 is excellent in good laser spot mode, enough power, long life, etc...
Working Principle: high-pressure discharge stimulate high concentration CO2 to generate laser.
Laser Wave Length: 10.6um.
Laser Mode:low order mode.
   Water-Cooling:purified water, appropriate temperature 10-35°C. 
Working Environment:temperature 5-35°C, humidity 10-60%, clean environment, no serious pollution.
Working Current:25~30mA is appropriate (excessive current will affect laser power and laser tube lifetime.
Safety Demand:CO2 laser tube outputs invisible light, positive with high pressure, if necessary, eyewear is essential.
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 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.
