Abstract: An investigation was made of the luminescence and lasing spectra of a calcium lithium niobium gallium garnet crystal activated with chromium, thulium, and holmium ions. Kinetics of decay of the Cr³⁺ luminescence was investigated and it was concluded that energy transfer from the Cr³⁺ to the Тm³⁺ ions was efficient. An investigation was made of the lasing characteristics of this crystal (λ_l = 2.09 μm) under free-running conditions at room temperature.
