Paper Abstract

Excited state absorption spectra of Cr4+-doped garnets and wurtzite-like crystals were measured between 400 nm and 2000 nm. In Cr4+:Y3Al5O12, a strong polarization dependence of the excited state absorption is observed, while it diminishes for Cr4+:Y3Sc0.5Al4.5O12 and is almost not observed in Cr4+:Y3Sc2Ga3O12. FOr Cr4+:LiAlO2 and Cr4+:LiGaO2 the region of the emission is overlapped by excited state absorption and nonlaser oscillation at room temperature is expected.
