Problems solved by technology

[0005] First of all, from the physical characteristics of the electrode discharge, in a strong electric field environment, the discharge part of the anode electrode is usually at its sharp tip, and the tip of the anode electrode is its end, so when the laser is working, the anode electrode The discharge is usually at its end, and because the outer wall of the anode electrode is closely attached to the inner wall of the anode chamber, the outer wall of the end is also closely attached to the inner wall of the anode chamber. High temperature, so that the local part of the anode chamber in contact with the discharge end of the anode has a high temperature, causing irregular deformation of the anode chamber, and in severe cases, it may also cause the local temperature of the anode chamber to be too high and burst , and the anode chamber will pull the gas storage tube when it is deformed. Since the two ends of the gas storage tube are equipped with output mirrors and reflective mirrors, when the gas storage tube is pulled, the alignment accuracy of the output mirror and the reflective mirror will decrease, thereby reducing the output of the laser. precision;
[0006] On the other hand, in order to fix the anode electrode and prevent the anode electrode from sliding in the anode chamber, during assembly, the end of the anode electrode close to the discharge tube is usually against the end of the water-cooled tube. Due to the obstruction of the water-cooled tube, the end of the electrode is discharged The part is not uniform and stable, that is, there is no discharge at the part closely attached to the end of the water-cooling tube, but there is constant or intermittent discharge at the part with a gap between the end of the water-cooling tube, and the inner wall of the anode electrode also occasionally Discharge phenomenon occurs. Due to the existence of this irregular discharge phenomenon, the quality of the laser beam generated by the laser is not stable, which directly leads to the decline in the quality of the laser product.

Abstract

The invention relates to the laser field, in particular to a carbon dioxide laser with a novel positive electrode structure. The carbon dioxide laser with the novel positive electrode structure comprises a gas storage pipe, a water cooling pipe and a discharging pipe which are arranged in sequence from the outside to the inside in a sleeve mode, the discharging pipe is provided with a positive electrode and a negative electrode and further provided with an anode chamber, the positive electrode is arranged in the anode chamber, the end of the positive electrode near the negative electrode is the discharging end, the discharging end of the positive electrode is separated from the inner wall of the anode chamber, and the discharging end of the positive electrode is further separated from the end of the water cooling pipe. The carbon dioxide laser with the novel positive electrode structure enables the irregular deformation amount of each of the anode chamber and the water cooling pipe to be weakened so that the pull on the gas storage pipe is weakened, and accordingly the influence on the alignment precision of an output lens and a reflecting lens is reduced, and the output precision of the laser is guaranteed.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a carbon dioxide laser with a novel positive electrode structure. Background technique [0002] Since the carbon dioxide laser has relatively large power and relatively high energy conversion efficiency, and its spectral lines are relatively rich, it has dozens of spectral lines near 10 microns in laser output, so it has been widely used in industry, military affairs, medical treatment, scientific research, etc. a wide range of applications.
