Half-reverse-flow-type high-strength carbon dioxide laser device

Abstract

The invention relates to the field of laser devices, in particular to a half-reverse-flow-type high-strength carbon dioxide laser device. The device comprises a gas storage pipe, a water cooling pipe and a discharging pipe, wherein the gas storage pipe, the water cooling pipe and the discharging pipe are sequentially arranged in a sleeved mode from outside to inside, the two ends of the discharging pipe are provided with an anode electrode and a cathode electrode respectively, the gas storage pipe is provided with a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are communicated with the water cooling pipe, the water inlet pipe is located on the water cooling pipe and is close to the end portion of the anode electrode, and the water outlet pipe is separated from the end portion, close to the cathode electrode, of the water cooling pipe. Compared with a laser device formed in the mode that a water inlet pipe and a water outlet pipe are arranged at the two ends of a water cooling pipe respectively, the laser device is formed in the mode that the water outlet pipe is a proper distance away from the end portion, lose to the cathode electrode, of the water cooling pipe, the span of the water cooling pipe between the water inlet pipe and the water outlet pipe is shortened firstly, then flexibility of the water cooling pipe is reduced when the laser device is impacted, the curvature degree of the water cooling pipe is reduced, the anti-impact capacity of the water cooling pipe is improved, and accordingly the anti-impact capacity of the carbon dioxide laser device is improved.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a semi-reflux high-intensity carbon dioxide laser. 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, a cathode electrode and an anode electrode respectively arranged at both ends of the discharge tube, and a gas storage tube arranged at both ends of the gas storage tube. The output window and reflective window at the end, the reflective window includes a reflective mirror and a reflective mirror cooling device, the outpu...

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
