This paper presents the principal results of work at the S. I. Vavilov
State Optical Institute on the manufacture of fluoride and leucosapph
ire single crystals, active laser crystals, and nonlinear and scintill
ation single crystals, as well as on optical ceramic obtained by recry
stallization pressing and zinc and cadmium chalcogenide polycrystals g
rown by the PVD, CVD, and MOCVD methods.
