Abstract: The Fe2 +∶ZnSe crystal has been prepared by thermal diffusion doping technique.The iron ions doping con-centration that was measured by Secondary Ion Mass Spectrometry (SIMS)in the crystal sample reaches 1.27 × 10 18 cm -3.The optical absorption spectrum of the Fe2 +∶ZnSe crystal was analyzed.The results show that a 2.90 μm laser is used to pump the Fe2 +∶ZnSe crystal at room temperature,67 mW average power of mid-infrared laser output at center wavelength 4.45 μm is obtained.
