Embodiment Construction
[0017] An anti-pollution method for a cavity mirror in an optical resonant cavity, the main idea of which is to use electrostatic force to remove pollutants such as liquid droplets, impurities and fine dust in a channel of a resonant cavity. In the process of ionization through the high-voltage electric field, the pollutant dust particles are charged, and the dust particles are deposited on the collector under the action of the electric field, thereby removing various pollutants and realizing the process of oxygen-iodine chemical laser light extraction. The mirror surface of the cavity mirror is not polluted, thereby improving the service life of the cavity mirror and ensuring the reliable operation of the system.
[0018] (1) First, the anti-pollution device module and the resonant cavity are designed as a whole;
[0019] (2) A magnetic corona dust collector is set between the optical cavity box and the mixing nozzle;
[0020] (3) The magnetocorona dust collector in the de...

The invention relates to a high-power oxygen-iodine chemical laser, in particular to a cavity-mirror anti-pollution method in an optical resonant cavity and a special cavity-mirror anti-pollution device. A magnetic-corona dust remover is arranged between an optical cavity box and an oxygen-iodine mixing thrust jet of the oxygen-iodine chemical laser; by adopting a low-air-pressure negative-direct-current high-voltage magnet to strength the corona discharge, the collection and the purification for electrical charges and pollutants can be carried out for polluted particles which pass through an optical cavity box inlet so as to reach the aim of preventing a cavity mirror from pollution. The invention adopts the cavity-mirror anti-pollution device which can effectively prevent the pollution of the polluted particles to the cavity mirror in the premise of not obstructing the normal running of the laser, thereby the aims of protecting an optical element and improving the output beam quality of the laser are realized.
Description
technical field [0001] The invention relates to a high-power oxygen-iodine chemical laser, in particular to a cavity mirror anti-pollution method and a special device in an optical resonant cavity. The present invention arranges the anti-pollution device of the cavity mirror between the generator and the cavity lens box. It adopts the new technology of sealed high voltage introduction, high-precision anti-bypass and high-efficiency charging of free electrons to realize low-pressure, large-pole-distance negative corona discharge electrostatic dust removal. Because the device can effectively prevent pollution particles from entering the cavity mirror box without hindering the normal operation of the laser, it can meet the requirements of the laser for the anti-pollution setting of the cavity mirror. Background technique [0002] As an important unit device of a laser, the cavity mirror is directly related to several key indicators (power, beam quality, and light emission time...
