Abstract
A new tunable laser material, Cr 4+:Ca 2GeO 4 (Cunyite), was investigated whose room-temperature fluorescence lifetime is five times longer if compared with its Cr:Mg 2SiO 4 (Cr:forsterite) analog by use of resonance Raman scattering. The relatively long lifetime in Cunyite indicates weaker nonradiative processes and better laser performance. Cr 4+ local modes are identified in Cunyite using resonance Raman scattering, at room temperature, with excitation wavelength 621.7 nm, corresponding to the 3A″→ 3A″( 3T 1) Cr 4+ dipole allowed transition. Cr 4+:Ca 2GeO 4 samples with 0.3% wt. were grown using the Czochralski method.
