A high-intensity carbon dioxide laser

Abstract

The present invention relates to the field of lasers, in particular to a high-intensity carbon dioxide laser, which includes a gas storage tube, a water-cooled tube and a discharge tube that are sequentially sleeved from outside to inside. The air pipe is provided with a water inlet pipe and an outlet pipe connected to the water-cooling pipe, and the distance between the position where one of the water inlet pipe and the water outlet pipe is connected to the water-cooling pipe is the distance from the end of the water-cooling pipe by the water-cooling pipe. 1 / 5~1 / 2 of the tube length. Compared with the laser in which the water inlet pipe and the water outlet pipe are respectively arranged at both ends of the water-cooled pipe, the laser of the present invention reduces the winding degree of the water-cooled pipe between the water inlet pipe and the water outlet pipe, and improves the structural stability and use accuracy of the carbon dioxide laser. The water-cooled tube is not easy to be damaged due to excessive bending, that is, the impact resistance of the water-cooled tube is improved, and the impact resistance of the carbon dioxide laser is also improved.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a high-intensity carbon dioxide laser. Background technique [0002] Due to the relatively large power and high energy conversion efficiency of carbon dioxide lasers, the spectral lines are also relatively rich, and the laser output with dozens of spectral lines near 10 microns 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-cooling tube sleeved outside the discharge tube, a gas storage tube sleeved outside the water-cooled tube, a cathode electrode and an anode electrode respectively disposed at both ends of the discharge tube, and a gas storage tube. The output window and the reflection window at the end, the reflection window includes the reflection lens and the cooling device for the reflection lens, the output window includes the output lens and the cooling...

Problems solved by technology

[0005] In the structure of the water-cooled tube and the discharge tube, the end of the water-cooled tube close to the anode electrode is fixedly connected to the gas storage tube and connected to the water outlet pipe, while the end of the water-cooled tube close to the cathode electrode is suspended and connected to the water inlet pipe, so The water pipe and the water outlet pipe not only play the role of water in and out, but also support and fix the cooling water pipe and the discharge tube. Therefore, the current water-cooled pipe and the discharge tube are fixed at the In the gas storage tube; since the carbon dioxide laser has a slender structure, its water-cooled tube is also a slender structure, so that the water-cooled tube supported at both ends has a long span, and when it is stored, transported, and used, the carbon dioxide laser is usually They are all placed in a horizontal state, so the water-cooled pipe between the water inlet pipe and the water outlet pipe is bent due to the influence of its own gravity, resulting in a large degree of winding. The existence of this large disturbance not only reduces the carbon dioxide laser Structural stability and accuracy of use, especially during transportation, when the packing box is impacted, when the impact is transmitted to the carbon dioxide laser, the water cooling pipe between the water inlet pipe and the water outlet pipe will be further bent, and the winding degree will be further increased. Large, when the bending degree is too large, the water-cooled tube will be damaged and fractured, resulting in damage to the carbon dioxide laser
