Abstract: The characteristics of a room-temperature laser based on a polycrystalline Fe²⁺:ZnSe sample pumped by a non-chain HF laser are studied. The laser energy is E = 175 mJ at the efficiencies with respect to the incident and absorbed pump energy η_p ≈ 22% and h_abs ≈ 29%, respectively.

Keywords: Fe²⁺:ZnSe laser, non-chain HF laser, optical pumping.
