摘要
Fe2+∶ZnSe晶体作为3~5 μm波段极具潜力的中红外激光介质之一, 在材料特性和转换效率等方面具有明显优势。对Fe2+∶ZnSe晶体的吸收特性进行了研究, 利用自制放电引发的非链式脉冲HF激光抽运Fe2+掺杂浓度为4×1018 cm-3、尺寸为10 mm×10 mm×5 mm的Fe2+∶ZnSe 晶体, 在室温下获得了65 mJ 的高能量Fe2+∶ZnSe中红外激光输出, 光光转换效率为31%, 输出激光能量相对于晶体吸收抽运光能量的斜率效率可达37%。
Abstract
As one of the most promising mid-infrared laser mediums in 3-5 μm wavelength region, Fe2+∶ZnSe crystal has many advantages in material property and conversion efficiency. The absorption characteristic of Fe2+∶ZnSe is investigated. A Fe2+∶ZnSe crystal with size of 10 mm×10 mm×5 mm and Fe2+ doping concentration of 4×1018 cm-3 is excited by a non-chain electric-discharge pulsed HF laser at room temperature. The maximum output energy reaches 65 mJ and the optical to optical conversion efficiency is 31%. The slope efficiency respecting to the absorbed pump energy is 37%.
