Structure laser with support barrel

Abstract

The invention relates to the field of lasers, in particular to a structure laser with a support barrel. The laser comprises a reservoir pipe, a water-cooling pipe and a discharge tube, wherein a reflecting lens is arranged at one end of the reservoir pipe and an output lens is arranged at the other end of the reservoir pipe; the water-cooling pipe is sleeved with the reservoir pipe; the discharge tube is sleeved with the water-cooling pipe; two ends of the water-cooling pipe and the discharge tube are in closed connection separately; and a support barrel structure sleeves outside the water-cooling pipe and elastically supports the water-cooling pipe in the water-cooling pipe. By the laser, on one hand, the direct alignment accuracy of the reflecting lens and the output lens is ensured to improve the output quality of a laser beam; and on the other hand, the risk of relative slippage between a support part and the water-cooling pipe and the discharge tube is reduced to reduce the risk that the reservoir pipe and the water-cooling pipe are scratched by the support part is reduced. Therefore, the reliability of the laser is improved and the service lifetime is prolonged.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a laser with a support cylinder structure. 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 discharge tube is fil...

Problems solved by technology

[0006] However, with further in-depth research, the inventor found that the support frame of the current structure still has deficiencies, specifically: firstly, the discharge tube can be well supported in the direction along the legs, but between the legs However, the part between them cannot be well supported, and during the process of transportation, the impact on the laser may come from any direction, so this kind of support is actually not reliable; on the other hand, during the working process of the laser, As the working time increases, the temperature of the laser rises, causing a certain amount of deformation in the radial and axial directions of the laser. However, the temperature growth among the discharge tube, water-cooled tube and gas storage tube is not consistent. Therefore, in the laser When thermal deformation occurs, the support frame will have a certain amount of sliding between the gas storage tube and the water cooling tube, which is very easy to scratch the gas storage tube and water cooling tube, reducing the service life of the laser; The support frame is close to the water cooling tube and the air storage tube. When the support frame does not slide, it will constrain the thermal deformation of the water cooling tube and the air storage tube in the axial direction, reducing the coaxiality of the water cooling tube and the air storage tube, resulting in the output lens and Reduced alignment accuracy of reflective mirrors reduces laser beam quality
