中波红外激光器在痕迹量气体检测、激发惰性气体产生软硬X射线辐射、激光定向干扰等方面具有重要应用价值。华北光电技术研究所采用硒化锌(Zn Se)晶片为基质材料,硒化亚铁(Fe Se)粉末为掺杂物,通过热扩散掺杂技术获得了尺寸Φ22 mm×4 mm、铁离子掺杂浓度3.43×1018cm-3的掺铁硒化锌(Fe2+:Zn Se)晶体样品。制备的Fe2+:Zn Se晶体在3.0μm附近处出现了明显的Fe2+离子特征吸收峰,吸收峰峰值处透射率为
Medium wave infrared laser has important application value in trace gas detection, excitation of inert gas to produce hard and soft X-ray radiation and laser directional interference. North China Institute of Optoelectronics Technology using zinc selenide (Zn Se) wafer as the matrix material, ferrous selenide (Fe Se) powder as a dopant, obtained by thermal diffusion doping technology size Φ22 mm × 4 mm, iron ion doped Doped iron-doped zinc selenide (Fe2 +: ZnSe) with a concentration of 3.43 × 10 18 cm-3. The prepared Fe2 +: ZnSe crystals showed obvious characteristic absorption peak of Fe2 + ions in the vicinity of 3.0μm, and the transmittance at peak absorption peak was
