Abstract: Efficient room-temperature lasing is obtained in a Fe²⁺:ZnSe crystal pumped by 2.9364-μm giant pulses from an Er:YAG laser. The slope efficiency of a Fe²⁺:ZnSe laser with respect to the absorbed pump energy is 13%. The laser with a dispersion resonator can be continuously tuned from 3.95 to 5.05 μm. The luminescence lifetime of the ⁵T₂ level of the Fe²⁺ ion in a ZnSe matrix at room temperature is measured to be 355±15 ns.
