Carbon dioxide laser

Abstract

The invention discloses a carbon dioxide laser. The carbon dioxide laser comprises a gas storage tube (5), a water cooling tube (6) and a discharge tube (7), wherein the water cooling tube (6) is sleeved on the outside of the discharge tube (7), the air storage tube (5) is sleeved on the outside of the water cooling tube (6), a positive electrode (1) and a negative electrode (10) are respectively arranged in an anode resonant cavity (2) and a cathode resonant cavity (9) of the discharge tube (7), a water inlet pipe (8) and a water outlet pipe (3) are respectively arranged at two ends of the water cooling tube (6), the anode resonant cavity (2) is communicated with the air storage tube (5) through a gas return tube (4) wound around the outside of the water cooling tube (6), a bump (11) is arranged in the middle of the gas storage tube (5), and the inner diameter of the bump (11) is greater than the inner diameters of two ends of the gas storage tube (5). The carbon dioxide laser has the advantages that bending strength of the product is increased, stability of the product is increased, output power is stable, working gas storage capacity is improved, and service life is improved greatly.

Description

[0001] This case claims the priority of the Chinese invention patent filed on September 25, 2012, with the application number 201220492284.7. technical field [0002] The invention relates to a carbon dioxide laser. Background technique [0003] Carbon dioxide lasers can be called "invisible people". The microwave light length it emits is 10.6 microns, and its "body" is in the infrared region, which cannot be detected by naked eyes. It has been widely used in machinery, military, medical, chemical and other fields. At present, the commonly used gas storage tubes of carbon dioxide lasers are straight tubes. When assembling the whole machine, carbon dioxide lasers of the same length and different diameters can only be installed on laser machines of different specifications. [0004] In the carbon dioxide laser, gas such as carbon dioxide is stored in the gas storage tube, and the two ends of the gas storage tube are used as the installation ends of the carbon dioxide laser to ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the disadvantages of poor versatility and unstable output power of lasers in the prior art. After increasing the diameter of the laser beam to increase the laser beam intensity, it is necessary to redesign and manufacture the laser machine that matches the carbon dioxide laser, resulting in a significant increase in cost. Provide One, with good versatility, stable output power, and high laser beam intensity, and does not need to design a carbon dioxide laser that matches the laser machine
