Six-μm laser generation at room temperature was achieved from Fe-doped CdMnTe solid-solution active media for the first time, to the best of our knowledge. Laser properties of Fe:CdMnTe crystals with various concentrations of manganese Mn (x=0.1, 0.52, 0.56, 0.68, and 0.76) were investigated. The increase of Mn content in these crystals was shown to result in an almost similar long-wavelength shift of absorption, fluorescence, and laser output spectra of about ∼60 nm per each 10% of Mn. Laser generation was achieved in all crystals with maximum output energies up to 30 μJ (for x=0.52). The laser central oscillation wavelength is significantly influenced by Mn concentration and varies in the range from 5400 nm up to 6000 nm.
首次在室温下从掺铁的 CdMnTe 固溶体活性介质中实现了 6μm 激光产生，据我们所知。研究了锰（x=0.1、0.52、0.56、0.68 和 0.76）浓度不同的 Fe：CdMnTe 晶体的激光特性。这些晶体中锰含量的增加导致吸收、荧光和激光输出光谱的长波长位移几乎相同，每增加 10%的锰约为 60nm。所有晶体都实现了激光产生，最大输出能量高达 30μJ（x=0.52）。激光的中心振荡波长受 Mn 浓度的显著影响，范围从 5400nm 到 6000nm。
