Description

technical field [0001] The invention belongs to the technical field of surface cleaning of large-diameter optical elements, and in particular relates to a device for realizing surface cleaning of optical elements through ion wind and electrostatic coupling. Background technique [0002] There are a large number of large-diameter optical components such as lenses, windows, reflectors, and transmission mirrors in high-energy laser systems. The cleanliness of optical components plays a vital role in the stable operation of the system, and the failure mode of optical components is mainly caused by laser damage. The stable and continuous operation of the device is of great significance. [0003] In high-energy laser facilities, various pollutants adhering to the surface of optical components are also closely related to surface damage. Under the action of high-energy laser, particle pollutants are plasmaized, and high-temperature and high-speed plasma causes burn damage to optica...
