A CO2 laser with new structure

Abstract

The invention relates to a carbon dioxide laser with new structure. Sealing and connecting metal structures at two sides can adjust the angle of a lens (1) and a lens (12); the major structure of the laser pipe shaft comprises a glass material discharge tube (20), a jacket pipe (19), an air-storing pipe (18), an air-returning pipe (17), a water inlet (16) and a water outlet (6); a resonant cavityis composed of a total reflective mirror (1) and an output mirror (23); an angle adjusting system for the total reflective mirror comprises a fixed flange (5), an adjustable flange (3), a soft metal gasket (13) and an adjusting screw (2); the metal structure of the angle adjusting system is sealed and connected with the glass structure of the laser pipe shaft by spacer flange chips (14)(9); a high pressure protective sleeve (24) plays a role in protecting the laser metal structure part with a high pressure; an output mirror protective sleeve (23) plays a role in protecting the output mirror (12) and releasing heat. The carbon dioxide laser is mainly applicable to the laser cutting and the carving machine tool with medium and small power and material processing.

Description

Technical field: [0001] The invention is a low-power, sealed-off carbon dioxide laser with a glass discharge tube structure, which can be applied to laser cutting, engraving and other equipment. Background technique: [0002] In the current field of small and medium power sealed-off carbon dioxide lasers, there are mainly two structures, a metal cavity RF-excited carbon dioxide laser, which has high production costs and is mainly used for laser marking; the present invention relates to another glass A DC high voltage electric excitation carbon dioxide laser with a discharge tube structure. Check the Chinese Patent Publication No. CN2862437, its title is sealed off type carbon dioxide laser, and it is described in this way: a kind of sealed off type carbon dioxide laser has a gas storage tube, and a water cooling tube is arranged in the gas storage tube, and the water cooling tube is connected with the inlet and outlet water pipes, A discharge tube is set in the water-cooled...

AI Technical Summary

Problems solved by technology

Compared with the earlier glass tube lasers on the market, this laser has no obvious features and advantages. Its structure has the following disadvantages with the lasers currently on the market: the current lasers all directly bond the full reflection mirror and the output mirror on the Glass nozzle, and the grinding accuracy of the nozzle is difficult to meet the expected requirements, so that the product quality consistency is not high, and the output power and mode are difficult to be in the best state

At present, the electrodes of the laser are introduced by the metal rods sintered on the glass shell. The sintering process is difficult, but the laser device has high requirements for vacuum sealing, so it is difficult to improve the product qualification rate, and such a structure when the electrode is near When the lens is a semiconductor or conductor, the electrode will discharge the lens, destroy the lens film, and affect the stable use of the product
