Description

Technical Field

[0001] The utility model belongs to the technical field of lasers, and particularly relates to a radio frequency CO2 laser with a coaxial red light device. Background Art

[0002] Carbon dioxide laser is a type of laser, which is a gas laser that uses CO2 gas as the working substance. The discharge tube is usually made of glass or quartz material, filled with CO2 gas and other auxiliary gases (mainly helium and nitrogen, usually with a small amount of hydrogen or xenon); the electrode is generally a nickel hollow cylinder; one end of the resonant cavity is a gold-plated full reflector, and the other end is a partial reflector made of germanium or gallium arsenide. It has two working modes: continuous and pulsed, and is used for laser cutting, welding, drilling and surface treatment.

[0003] Since CO2 lasers are invisible, the CO2 lasers currently on the market can only be installed separately at a location that is not coaxial with the laser emitted by the CO2 laser when they need to work in conjunction with red light. The position and angle need to be adjusted to achieve the best coaxial effect. At the same time, various factors such as installation space must also be considered, and the operation process is relatively complicated. Utility Model Content
