Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a device for detecting and discharging particles in a laser cavity. Background technique [0002] At present, high-power (ultra-high-power) lasers are more and more widely used in the industrial and military fields, because of their high cost, complex structure and long maintenance period, so the reliability index of high-power lasers is becoming more and more important. However, the surface of the optical device in a high-power laser carries a very high laser power density. When the surface of the optical device absorbs the microparticles in the cavity of the laser, it will cause local heat to accumulate sharply, resulting in damage to the coating on the surface of the optical device or damage to the beam. The quality deteriorates, reducing the reliability of high-power lasers. [0003] Existing laser intracavity microparticle removal technologies mainly include: vacuum cleaner ...

Problems solved by technology

[0007] The object of the present invention is to provide a particle detection and discharge device in the laser cavity, which is used to solve or partially solve the problem that most of the existing micro-particle removal technologies in the high-power (ultra-high-power) laser cavity cannot perform close-range inspection on the surface of the internal device. Strong suction to exclude microparticles, and technical problems that cannot be visually inspected to ensure that microparticles in the cavity are completely excluded
