Abstract

The invention provides a carbon dioxide laser. The carbon dioxide laser comprises a laser generating module and a laser output path. The laser generating module is used for generating laser. The laser output path sequentially includes a plane mirror and a focusing mirror. A first gas purger is disposed in an area below the focusing lens. Gas flow from a gas outlet of the first gas purger is used for purging the area below the focusing mirror. A heading direction of the gas flow from the gas outlet of the first gas purger is horizontal and is perpendicular to a heading direction of laser from the focusing mirror. The first gas purger disposed in the rear below the focusing mirror can be used for gas flow protection under the focusing mirror, and damage of the focusing mirror, or the carbon dioxide laser, can be prevented.

Description

[0001] technical field [0002] The invention relates to a carbon dioxide laser and belongs to the field of laser equipment. [0003] Background technique [0004] A laser is a device that emits laser light. In 1954, the first microwave quantum amplifier was made and a highly coherent microwave beam was obtained. In 1958, A.L. Xiao Luo and C.H. Towns extended the principle of laser microwave quantum amplifier to the optical frequency range, and pointed out the method of generating laser. In 1960, T.H. Maiman and others made the first ruby ​​laser. In 1961, A. Jia Wen and others made a helium-neon laser. In 1962, R.N. Hall and others created a gallium arsenide semiconductor laser. [0005] There are many types of lasers. According to the different states of working substances, all lasers can be divided into the following categories: the first category, solid-state lasers (crystal and glass) lasers; the second category, gas lasers, gas lasers can be further divided i...
