Room temperature lasing of a set of Cd1-xMnxTe solid-solution crystals doped with Fe2+ ions was obtained under optical pumping by 4.1 mu m 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 non-radiative fluorescence quenching.
