Abstrakt: The effective peak stimulated-emission cross section of chromium-doped gadolinium–scandium–gallium garnets (GSGG) has been determined to be 8.5 × 10^−21 cm^2 at room temperature. The values of the energy-gap ΔE(^2E − ^4T_2) chromium fluorescence lifetime and the chromium ? neodymium energy-transfer parameter CDA(Cr–Nd) are determined for several gallium garnets. Temperature-dependent absorption and luminescence spectra of neodymium-doped GGG and GSGG are reported and discussed in the context of their use as laser materials.
