METHOD FOR GENERATING OPTICAL DISCHARGE Russian patent published in 2023 - IPC H01J61/02 H01J65/04 

FIELD: optical equipment.

SUBSTANCE: invention relates to a method for generating an optical discharge in order to obtain broadband optical radiation with high spectral brightness and is of interest for applications in microelectronics, spectroscopy, photochemistry and other fields. In the method of generating an optical discharge, which consists in maintaining an optical discharge located in the discharge chamber, laser radiation is supplied to a thin-film polarizer at the Brewster angle. The reflected beam with s-polarization is directed through an appropriate quarter-wave plate, reflected from two mirrors, and focused in the discharge volume. A passing beam with p-polarization is directed through an appropriate quarter-wave plate and focused in the discharge volume. To ignite an optical discharge, laser radiation is directed to a thin-film polarizer, a laser pulse is applied, a radiation absorber is installed, the return rays reflected from plasma are reflected from two mirrors, passed through quarter-wave plates, directed to the thin-film polarizer and transferred to the radiation absorber.

EFFECT: expansion of the range of technical means.
