Room temperature high energy Fe:ZnSe laser pumped by non-chain pulsed HF laser

Abstract

Pulsed lasing of Fe:ZnSe polycrystalline sample was demonstrated at room temperature. The characteristics of Fe: ZnSe laser pumped by a non-chain pulsed HF laser were studied. The laser action centered at 4.3 um. The Fe:ZnSe sample were prepared by using thermo diffusion technique. The threshold of absorbed pump HF laser energy of was 20 mJ, the maximum laser energy was E=15 mJ at the efficiency η ab =15% with respect to the absorbed HF laser energy.
