Puri Laser, Stronger Power!
Some advantages of Puri laser tube:

1.We are the only manufacture which can produce from 40W laser tube to 400W laser tube. -- Can meet all your needs for CO2 glass tube;
2.Catalyst coating on discharge tube with unique electrode processing makes the laser output more stable;
3.All the tubes ≥80W can reach 8000-10000 hours lifespan.
4.Power is strong. Max power of 100w can reach 120W, max power of 150w can reach 180W.
5.Spot is small, circular, briliant and solid. When texting in acrylic, the hole in acrylic is small, deep and subuliform. 
6.Used imported mirror, material is ZnSe while some other manufacture uses Ge.


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.

Until now, Puri laser tubes are sold to more than 60 countries in the world.
