CO2 laser tube full name should be: glass sealed-off CO2 laser. Because this laser is a glass packaging is made, it is known as the laser tube. How it works: the high-pressure gas discharge excitation high concentrations of CO2 produced 10.6um the wavelength of the laser. Knowledge laser tube consisting essentially of hard glass, resonator, electrodes of three parts. 1, hard glass part; the part formed by firing into the discharge tube GG17 material, water-cooled jacket, storage units and back to the trachea and components. Sealed-off CO2 laser is typically three pipe structure. Innermost discharge tube, the middle is the net water jacket, the outermost layer is the gas storage units, return pipe is used for communicating and gas discharge tubes. 2, cavity parts: the part formed by totally reflecting mirror and output mirrors. Full-mirror cavity generally with optical glass substrate, the surface of gold film, a gold film mirror reflection over 10.6um near 98%; output mirror resonator generally use infrared radiation transmissive material germanium 10.6um (Ge) as a substrate coated with the above dielectric multilayer film made. 3, the electrode portions: CO2 lasers generally use cold cathode is cylindrical in shape, the choice of the cathode material has a great influence on the life of the laser, the basic requirements for cathode materials are: sputtering rate, gas absorption rate is small laser tube Main Specifications Model laser power as the most important basis. Common model:. 15W, 25W, 40W, 60W, 80W different power laser tube is mainly divided into different lengths. As 60W laser tube of 1200mm or 1250mm, 80W length is generally 1600mm. Mainly used for CO2 laser tube laser processing equipment. Such as laser engraving machine, laser cutting machine, laser marking machines.
