Output lens cooling device of carbon dioxide laser

Abstract

The invention relates to carbon dioxide laser devices, in particular to an output lens cooling device of a carbon dioxide laser. The output lens cooling device comprises an inner sleeve (1) and an outer sleeve (2) which are coaxially arranged, a base plate (3) is arranged between the inner sleeve (1) and the lower end of the outer sleeve (2), a flowing path (4) is formed between the inner sleeve (1) and the outer sleeve (2), an inlet tube (5) and an outlet tube (6) are arranged on a lateral wall of the outer sleeve (2), the inlet tube (5) and the outlet tube (6) are communicated with the flowing path (4), and the output lens cooling device is characterized in that the upper end of the flowing path (4) is opened, a cover plate (7) for sealing the flowing path (4) is arranged at the upper end of the outer sleeve (2), and a groove (11) is arranged on a lateral face of the cover plate (7). The output lens cooling device of the carbon dioxide laser separates the cooling device into two portions, the flowing path (4) is covered by the cover plate (7), processing and manufacture can be conveniently carried out, and accordingly the cooling device can be produced in mass.

Description

technical field [0001] The invention relates to a carbon dioxide laser device, in particular to a carbon dioxide laser output mirror cooling device. Background technique [0002] Carbon dioxide laser is a gas laser with carbon dioxide gas as the working substance. The discharge tube is usually made of glass or quartz material, which is filled with carbon dioxide gas and other auxiliary gases; the electrode is generally a hollow cylinder made of nickel; one end of the resonant cavity is a reflector lens, and the other end is the output lens. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, and a laser beam is formed after being reflected by the output mirror and the reflective mirror. Carbon dioxide lasers have relatively large power and relatively high energy conversion efficiency, and the spectral lines are also relatively rich. There are dozens of spectral lines near 10 microns. The laser output has been widely used in ...

Problems solved by technology

[0007] The purpose of the present invention is: to solve the problems existing in the prior art that machines cannot be used to realize mass production; the glass is fragile, and it is easy to cause damage due to collision during transportation, installation or use; at the same time, the thermal conductivity of the glass material is relatively poor. The cooling effect and cooling efficiency are relatively low, and it cannot be firmly bonded to the output lens at the end of the carbon dioxide laser glass sleeve. It provides a method that is convenient for mass processing and production, is not easy to damage, especially has good thermal conductivity and cooling efficiency. High, and a carbon dioxide laser output mirror cooling device that can be firmly bonded to the output mirror at the end of the carbon dioxide laser glass sleeve
