Fe2+ doped materials are attracting growing interest as a source of tunable radiation in mid IR (46 um) spectral region. Highly efficient pulsed and CW operation of Fe2+ ions in ZnSe crystals have been already demonstrated [1,2]. The 5.1 um limit of Fe2+ ions tuning range in ZnSe crystal can be overcome by using different Se-based solid solutions like Zm-xMnxSe, Zm-xMgx Se or Te-based solid solutions like Zn1-xMnxTe, Cd1-xMnxTe. Results on influence on matrix composition as well as excitation wavelengths on spectroscopic and laser properties of Fe2+ ions for a wide range of Mn concentrations x and temperatures will be presented and discussed. Applying of solid-solutions technique will be shown to allow Fe2+ ions central oscillation wavelength shift from 4.5 um in ZnSe crystal up to 5800 nm in Se-based and up to 5950 nm in Te-based solid solutions at room temperature. Advantages of solid solutions for Cr2+ co-doping allowing to obtain efficient Cr2+-Fe2+ energy transfer for further Fe+2 ions lasing will be discussed.
