METHOD OF PRODUCING OPTICAL DISCHARGE Russian patent published in 2024 - IPC H01J61/02 

FIELD: physics.

SUBSTANCE: invention relates to a method of producing an optical discharge in order to generate broadband optical radiation with high spectral brightness and is of interest for applications in microelectronics, spectroscopy, photochemistry and other fields. Laser radiation is supplied to the polarization cube at the Brewster angle passing through the polarization cube, the p-polarization beam is passed through the corresponding quarter-wave plate and focused in the discharge volume, beam with s-polarization reflected from the polarization cube is passed through the corresponding quarter-wave plate, reflected from two mirrors and focused in the discharge volume. Mirrors are arranged so that the beams intersect in the discharge volume, and the angle between the beams is more than 60 degrees. Return beams reflected from the plasma with polarization changed relative to the direct beams are transmitted along their optical paths back to the polarization cube and are diverted to the radiation absorber.

EFFECT: wider range of equipment.
