METHOD OF PREPARING OF OPTIC POLYCRYSTALLIC BLOCKS OF ZINC SELENIDE Russian patent published in 1994 - IPC

Abstract RU 2019586 C1

FIELD: optoelectronics, laser technology. SUBSTANCE: polycrystallic blocks are prepared by gas-phase precipitation of zinc selenide containing silicon at concentration (2-6) x 10^-3 wt.-% on the heated backing. Transparency of blocks treated after growing at the wavelength 10.6 microns is 70-71%. EFFECT: improved method of polycrystallic block making. 1 tbl
