A high stability carbon dioxide laser cooled by reflux

Abstract

A highly stable carbon dioxide laser that is cooled by recirculation. The carbon dioxide laser comprises a gas storage tube (1), a water cooling tube (2) and a discharge tube (3) sequentially sleeved one over the other from the outside inward; the two ends of the gas storage tube (1) are respectively provided with a reflective lens (4) and an output lens (5); the gas storage tube (1) is provided with a water inlet tube (7) and a water outlet tube (6) connected to the water cooling tube (2); the water cooling tube (2) is a double-layer structure comprising an inner-layer water cooling tube (8) connected to an outer-layer water cooling tube (9); the water inlet tube (7) and the water outlet tube (6) are respectively connected to the inner-layer water cooling tube (8) and the outer-layer water cooling tube (9); the water inlet tube (7) and the water outlet tube (6) are disposed at the same end of the water cooling tube (2). The deformation of the water inlet tube (7) and the water outlet tube (6) has reduced impact on the cylindricity of the gas storage tube (1), thus allowing use of a constant temperature device with low constant temperature precision to reduce costs, or even to eliminate the constant temperature device and further reduce costs.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a high-stability carbon dioxide laser cooled by reflux. Background technique [0002] Due to the relatively large power and relatively high energy conversion efficiency of carbon dioxide lasers, the spectral lines are relatively rich, and there are dozens of spectral lines near 10 microns. The laser output has been widely used in industry, military, medical, scientific research, etc. Applications. [0003] The current carbon dioxide laser usually includes a discharge tube, a water-cooled tube set outside the discharge tube, a gas storage tube set outside the water-cooled tube, electrodes arranged at both ends of the discharge tube, and output windows and reflectors set at both ends of the gas storage tube. Window, the reflective window includes reflective mirror and reflective mirror cooling device, the output window includes output mirror and output mirror cooling device, and the discharg...

Problems solved by technology

[0009] However, after using the constant temperature device, firstly, the production cost is greatly increased, and secondly, the use of the carbon dioxide laser is more complicated, the volume increases, and it is inconvenient to transport and transport. In addition, the accuracy of the laser depends largely on the Due to the accuracy of the constant temperature device, but the current constant temperature device is difficult to be completely in a constant temperature state, so the stability of the laser beam output quality of the laser is still not high
