Abstract

Room temperature lasing of a set of Cd_1-xMn_xTe solid-solution crystals doped with Fe²⁺ ions was obtained under optical pumping by 4.1 μm liquid nitrogen cooled Fe²⁺:ZnSe laser. Oscillation wavelength maxima were found to increase linearly with Mn content x increase at a rate of about 60 nm per each 10 % of Mn content in the sample. The central oscillation wavelength as high as 5940 nm was obtained for sample with the highest Mn content (x = 0.76). The output energy was found to decrease for samples with higher Mn content due to very strong nonradiative fluorescence quenching.
