摘要：

Single crystals of a new promising laser material, Cr4+-doped germanium eucryptite Cr4+:LiAlGeO4, are grown from the melt for the first time. The crystals grown exhibit nonlinear optical properties. Absorption and luminescence spectra of the crystals and their luminescence decay are studied at various temperatures. The luminescence lifetime at 1.2 mu m at 300 K is 10 mu s. Active centers in the crystal are identified, and crystal field parameters are estimated. (C) 2000 MAIK "Nauka/Interperiodica".
