Description

Technical Field

[0001] The invention relates to the field of laser tubes, and in particular to an efficient, simple and clean gas pumping and filling structure. Background Art

[0002] Traditional laser tubes are basically disposable and have a service life of only a few thousand hours. New laser tubes must be replaced, which increases the user's cost of use. In addition, the gas tube on the traditional laser tube is made of glass. Therefore, after the laser tube is filled with gain medium or vacuum through the gas tube, it is sealed by glass sintering. This requires repeated cutting and sintering of the glass gas tube, which has a high failure rate and also places higher requirements on operators. For this reason, an efficient, simple and clean gas extraction and filling structure is proposed. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0004] An efficient, simple and clean gas pumping and filling structure comprises an L-shaped frame, wherein at least one group of laser tube bodies are transversely arranged inside the L-shaped frame, and pipelines are connected to gas guide pipes at both the front and rear ends of the side of the laser tube body, and the other end of the gas guide pipe is provided with a gas valve, and the gas valve is connected to a vacuum unit for replenishing a gain medium, and then the vacuum unit is connected to the laser tube body through the gas valve, so that the vacuum unit performs vacuum treatment on the inside of the laser tube body and replenishes the gain medium, and can be sealed or conducted at any time.

[0005] Preferably, the L-shaped frame is provided with a laser emission transmission platform, and the laser emission transmission platform is vertically located at one side outside the L-shaped frame, and a pipeline connection is established between the laser emission transmission platform and the laser tube body.

[0006] Preferably, a laser emitting prism is arranged between the laser emitting transmission platform and the laser tube body, and the laser emitting prism is obliquely arranged at the upper and lower ends of the laser emitting transmission platform, and the mirror surface of the laser emitting prism is located at the upper and lower ends inside the laser emitting transmission platform.

[0007] Preferably, a limiting frame is arranged between the L-shaped frame and the laser tube body, and the limiting frame is vertically arranged inside the L-shaped frame, and the laser tube body is laterally located at both sides of the limiting frame.

[0008] Preferably, the air valve is provided with a locking block, and the locking block is sleeved on the outside of the air valve, and the air valve is made of metal material.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the vacuum unit is connected to the laser tube body through the gas valve, so that the vacuum unit can seal or conduct at any time after vacuum processing the inside of the laser tube body and replenishing the gain medium, without sealing the gas tube by melting or cutting the seal of the gas tube by a micro tube cutting knife, thereby doubling the service life of the laser tube, avoiding frequent replacement of the laser tube, and achieving the purpose of reducing user use costs.
