Abstract: The superluminescence of a Fe²⁺:ZnSe crystal was obtained in the region from 4.6 to 4.7 μm upon transverse pumping by high-power laser radiation at 2.94 μm. The superluminescence pulse energy was ~1 mJ upon pumping by a 15-mJ pulse. A ZnSe crystal was doped with Fe²⁺ ions by the diffusion method under the conditions of the thermodynamic equilibrium of phases.
