CO2 Laser tube:

Working Principle: high-pressure discharge stimulate highconcentration CO2 to generate laser.??????
Laser Wave Length: 10.6um.??????
Laser Mode:low order mode.  
Water-Cooling: purified water, appropriate temperature 10-35Celsius degree. ??????
Working Environment:temperature 5-35 Celsius degree, humidity10-60%, clean environment, no serious pollution.???Working
Current:16~22mA is appropriate (excessive current will affect laserpower and laser tube lifetime.??????
Safety Demand: CO2 laser tube outputs invisible light, positivewith high pressure, if necessary, eyewear is essential.??????
Laser State: Laser power will be attenuated when the laser tube isused at a certain time; If the laser is pink, it is in
normal condition; if the laser is white, it means the laser poweris 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, whenyou install the laser tube, the two points should be in 1/4 of thelaser tube; 
2. On the basis of cooling water above-in and below-out, if yourotate the laser tube slightly, it will affect laser spot and laserpower.
