Abstract :
Different tungstates and molybdates have been examined in view of their potential application as host lattices for tunable Cr3+solid-state lasers. From chemical, crystal growth, and structural considerations, Cr:Al2(WO4)3and Cr:Sc2(WO4)3are suitable and have been investigated spectroscopically in detail. Due to the acentric site symmetry of the Cr3+laser ions (C1), both compounds exhibit strong absorption and emission cross sections in the 10-19cm2range and therefore belong to the class of high-gain Cr materials. For the first time, laser action has been observed in Cr : Al2(WO4)3at about 800 nm wavelength. Laser experiments with Cr:Sc2(WO4)3are in progress.
