OPTICAL ELEMENT OF LASER CAVITY FOR PRODUCING RADIALLY POLARIZED RADIATION Russian patent published in 2001 - IPC

Abstract RU 2173012 C1

FIELD: laser engineering; laser cavities. SUBSTANCE: optical element is, essentially, reflecting diffraction component that may be used as blind mirror in laser cavity; lines of reflecting diffraction component are deposited on working surface in the form of concentric circles with center on element axis; pattern period T = 2λ(1±0,1) and line depth h = 0,5λ(1±0,1), where λ is radiation wavelength. Polarization selectivity of laser-cavity optical element approaches 100%. EFFECT: enhanced selectivity of radial polarization. 1 dwg
