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.
