1. Laser tube’s hard glass part on laser die cutting machine; this part is made up of GG17 material to make discharge tube, water cooling sleeve, gas storage sleeve and return air tube. Sealed CO2 lasers are typically three-layered casing structures. The innermost part is the discharge tube, the middle is the water net sleeve, the outermost layer is the gas storage sleeve, and the return air tube is used to connect the discharge tube and the gas storage tube.

2. Laser tube’s resonator section on laser die cutter: This part consists of a full mirror and an output mirror. The full mirror of the cavity is generally based on optical glass, and the surface is gold-plated. The reflectivity of the gold mirror near 10.6um is over 98%. The output mirror of the cavity is generally made of infrared material that can transmit 10.6um. Ge (Ge) is a substrate, and a multilayer dielectric film is formed thereon.

3. Laser tube’s electrode part on laser die cutting machine: CO2 laser generally adopts cold cathode and has a cylindrical shape. The choice of cathode material has a great influence on the life of the laser die cutter. The basic requirements for the cathode material are: low sputtering rate and low gas absorption rate.

The main specifications of the laser tube are based on laser die cutting machine’s power. The current common models are: 15W, 25W, 40W, 60W, 80W.

Laser tubes of different powers are mainly distinguished by different lengths. For example, the 60W laser tube is 1200mm or 1250mm, and the 80W length is generally 1600mm.
