Description

Technical Field

[0001] The utility model relates to the field of lasers, in particular to a handheld lamp-pumped solid laser with an electromagnetic shielding protection mechanism. Background Art

[0002] Conventional lamp-pumped solid-state lasers are often equipped in the host computer, and the laser is output through space or light-guiding devices or light-transmitting media. With the increasing application of miniaturized lasers in military, scientific research, medical, medical beauty and industrial lasers, the demand for handheld lamp-pumped solid-state lasers is also increasing. Its characteristics are compactness and convenient handheld operation, but the distance between the laser generator and the human body is short, and direct contact with the metal shell poses a greater safety hazard. In addition, the use of space electromagnetic signals is very complicated, so a more complete shielding protection structure is needed to increase the safety of use.

[0003] The gas pulse lamp used as the pump source of lamp-pumped solid-state laser has a very high discharge voltage when working, so the entire laser generator has the risk of high-voltage leakage; at the same time, the gas pulse discharge lamp has a large discharge current, which will cause electromagnetic radiation to the space; and as an important laser generating device, the laser generator is also an important factor in resisting external interference signals. Therefore, handheld lasers need to be well protected from the leakage of their own electromagnetic radiation and shielded from external electromagnetic interference. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a handheld lamp-pumped solid-state laser with an electromagnetic shielding protection mechanism that reduces high-voltage leakage and prevents electromagnetic radiation.

[0006] The preferred technical solution includes a cooling water pipe, which is installed on a water joint on the focusing cavity, and the water joint is integrally formed with the focusing cavity. The cooling water enters the focusing cavity through the water inlet of the water joint, and a water layer is left between the solid laser working substance and the gas pulse lamp and the inner wall of the focusing cavity. The cooling water passes through the solid laser working substance and the gas pulse lamp in turn, and the heat generated by the gas pulse lamp during operation and the heat generated by the solid laser working substance when it is excited are taken out of the focusing cavity through the water outlet of the water joint.

[0007] According to a further technical solution, the electromagnetic shielding protection mechanism includes an insulating inner shell, a shielding net, an insulating layer, an insulating outer shell, and a protective tube. The insulating inner shell is covered on the outside of the laser generator, the shielding net is fixedly arranged on the outside of the insulating inner shell, the insulating layer is fixedly arranged on the outside of the shielding net, and the insulating outer shell is fixedly arranged on the outside of the insulating layer.

[0008] In the above technical solution, the insulating inner shell, the insulating layer and the insulating outer shell are all made of high-voltage resistant plastic insulating materials, and the protective tube can be made of hard or soft insulating materials according to the use requirements.

[0009] According to a further technical solution, the shielding net comprises a soft shielding net and a hard shielding net, wherein the soft shielding net is coated on the outside of the pulse lamp discharge wire and the cooling water pipe, and the hard shielding net is fixedly arranged on the outside of the insulating inner shell.

[0010] In the above technical solution, the hard shielding net and the soft shielding net are fully connected by welding to achieve an overall shielding effect. The tail end of the soft shielding net is connected to the ground wire. If a circuit leakage fault occurs in the laser generator during operation, the leakage current is led to the ground wire through the shielding mechanism for discharge.

[0011] According to a further technical solution, the protective tube is wrapped around the outside of the soft shielding net.

[0012] According to the preferred technical solution, a sealing ring is installed between the pressing block and the focusing cavity, and the sealing ring is squeezed by the pressing block to seal the gas pulse lamp and the solid laser working material on the focusing cavity.

[0013] The advantages of the utility model are:

[0014] 1. The utility model wraps an insulating layer with a sandwich outside the laser generator, and places a shielding net structure in the sandwich of the insulating layer. The shielding net has a protective ground terminal. While effectively shielding electromagnetic radiation, if the laser generator has a circuit leakage fault during operation, it can be led to the protective ground for discharge through the shielding mechanism, isolating the handheld laser high voltage and electromagnetic radiation from harming the human body, thereby improving the safety of the handheld laser;

[0015] 2. The utility model can pass the EMC electromagnetic compatibility test and is widely used in medical, scientific research, industrial, military and other fields. BRIEF DESCRIPTION OF THE DRAWINGS
