The present invention relates to a high power CO 2 Laser discharge area wind speed monitoring system, which belongs to high power CO 2 laser field. Solve the existing technology of high power CO 2 For the laser, it is necessary to judge whether the gas flow in the discharge area meets the working requirements of the laser through the light-emitting state of the laser after the overall laser is built, resulting in a technical problem that the debugging cycle is too long. The high power CO 2 The wind speed monitoring system in the laser discharge area includes a cover plate, an upper electrode plate, a lower electrode plate, a side support plate, a wind speed test probe, a sealing flange and a probe fixing plate, and the material of the cover plate is plexiglass. The high power CO provided by the present invention 2 Wind speed monitoring system in laser discharge area can be used to monitor high power CO 2 The flow state of the working gas in the laser discharge area to achieve high power CO 2 Multi-point and comprehensive wind speed detection in the laser discharge area, for high-power CO 2 Provide the basis for the selection of the fan of the laser.
Description
technical field [0001] The present invention relates to high power CO 2 The field of lasers, specifically a high power CO 2 Wind speed monitoring system in laser discharge area. Background technique [0002] high power CO 2 Lasers are widely used in many fields such as industry, medical treatment, military and scientific research. When the laser is working, the high voltage acts on the discharge area to ionize the working gas of the laser, and oscillates in the resonant cavity to form laser light. In order to obtain a high average power laser output, it is necessary to achieve a large volume of uniform and stable continuous glow discharge, which requires a stable flow rate of the working gas in the discharge area to avoid the formation of turbulent flow and other phenomena; during the working process of the laser, the photoelectric conversion efficiency of the gas discharge is generally It is about 15%, which means that about 85% of the injected electric energy is conver...
