DUSTPROOF STRUCTURE FOR LIGHT EMERGENT WINDOW SHEET OF LASER, AND LASER
Document Type and Number:
WIPO Patent Application WO/2023/040226
Kind Code:
A9
Abstract:
Provided in the present invention are a dustproof structure for a light emergent window sheet of a laser, and a laser. The dustproof structure for a light emergent window sheet of a laser comprises a discharge cavity body, a gas purifier, a dustproof pipeline and a fan, wherein an intermediate cavity is provided between the light emergent window sheet and a slit; an intake end of the dustproof pipeline passes through the intermediate cavity on the way to the gas purifier and is connected to the gas purifier; an output end of the dustproof pipeline is connected to the fan; at least part of a working gas purified by the gas purifier flows through the intermediate chamber by means of the dustproof pipeline; and the fan drains the working gas, so as to increase the flow of gas passing through the intermediate cavity, such that the sweeping of the light emergent window sheet by clean gas is enhanced, thereby effectively preventing particulate matter in the working gas, which enters the intermediate cavity from the discharge cavity body and passes through the window on the slit, from approaching and contaminating the light emergent window sheet.
