Abstract

We report the Cr²⁺ → Fe²⁺ ions energy transfer under ~1.73 µm excitation of the Cr²⁺,Fe²⁺:Zn_1-xMn_xSe (x ≈ 0.2) single crystal for the first time and the results were compared with the crystal containing ~2× higher manganese amount (x ≈ 0.4) in the host material. Mid-infrared laser generation from Cr²⁺ ions at ~2.3 µm and ~2.5 µm, and from Fe²⁺ ions at ~4.4 µm and ~4.75 µm of the x ≈ 0.2 and x ≈ 0.4 samples, respectively, is presented.
