Laser tube, full name of the glass sealed off CO2 laser, because the structure is made of glass packaging, it is commonly known as the laser tube. The laser tube is mainly composed of hard glass, resonant cavity and motor. The working principle of the laser tube is high-pressure discharge high-concentration CO2 gas generating laser, mainly used for laser engraving machine, laser cutting machine, laser marking machine and other equipment .

　　The general laser tube has 80W, 100W, 120W, 130W, 150W and 180W, and want to understand how the laser tube, the main need to understand its life, laser energy, spot quality, laser tube stability and its power.
