Abstract: An investigation was made of the spectral, luminescence, and lasing characteristics of gadolinium scandium aluminum garnet (GSAG) doped with chromium and neodymium. It was found that at the working activator concentrations, GSAG crystals are not inferior to gadolinium scandium gallium garnet crystals in terms of the efficiency of excitation energy transfer from the chromium to the neodymium ions. The maximum differential efficiency of 2.4% was obtained under free-running conditions.
