Aa. Kaminskii et al., Optical and nonlinear laser properties of the X-(3)-Active monoclinic alpha-KY(WO4)(2) crystals, CRYSTALLO R, 46(4), 2001, pp. 665-672
Monoclinic alpha -KRE(WO4)(2) crystals are grown. Their structure is descri
bed in two crystallographic settings. The principal refractive indices are
determined and the coefficients and characteristic wavelengths are used for
calculating refractive indices by the Selmeyer formulas. The data on the a
nisotropic parametric Raman generation in these crystals under the picoseco
nd pumping are discussed. (C) 2001 MAIK "Nauka/Interperiodica".
