Abstract

The spectroscopic properties of Cr2+, Co2+, and Ni2+-doped single crystals of ZnS, ZnSe, and ZnTe have been investigated to understand their potential application as mid-IR tunable solid-state laser media. The spectroscopy indicated divalent Cr was the most favorable candidate for efficient room temperature lasing, and accordingly, a laser-pumped laser demonstration of Cr:ZnS and Cr:ZnSe has been performed. The lasers’ output were peaked at ~2.35 μm and the highest measured slope efficiencies were ~20% in both cases.
