摘　　要：本文采用纯度为99.999%的颗粒状ZnSe为基质材料,纯度为99.998%的FeSe粉末为掺杂物,通过HPVB法生长了Fe^(2+):ZnSe晶体,晶体尺寸达Φ50.8 mm×120 mm。采用电感耦合等离子发射光谱仪测试了Fe^(2+):ZnSe晶体样品中铁离子掺杂浓度为3.048×10^(18)cm^(-3)。采用粉末XRD衍射仪测试了Fe^(2+):ZnSe晶体样品的X-射线衍射谱,其衍射谱与基质ZnSe样品衍射谱匹配度达92%。采用UV/VIS/NIR分光光度计和傅里叶红外光谱仪测试了Fe^(2+):ZnSe晶体样品的透过谱图,透过谱在波长3.0μm处出现了明显的Fe^(2+)离子吸收峰。采用2.94μm Er:YAG激光器为泵浦源抽运尺寸为10 mm×10 mm×4 mm的Fe^(2+):ZnSe晶体样品,重复频率为100 Hz时,激光能量输出达12 mJ,输出波长调谐范围3.95~4.15μm。In this paper,Fe^(2+):ZnSe crystal with the size ofΦ50.8mm×120mm is grown by using 99.999%granular ZnSe as the substrate material and 99.998%purity FeSe powder as the dopant through high-pressure vertical Bridgman(HPVB)method.The iron-ion doping concentration in the Fe^(2+):ZnSe crystal sample is 3.048×10^(18)cm^(-3),which tested by the inductively-coupled plasma emission spectrometer.The X-ray diffraction spectrum of Fe^(2+):ZnSe crystal sample is investigated by the powder XRD diffraction instrument,showing a matching degree between the diffraction peak and the crystal sample is 92%.The transmission spectroscopy of Fe^(2+):ZnSe crystal sample is measured using a UV/VIS/NIR spectrophotometer and a Fourier infrared spectrometer,presenting a significant Fe^(2+)ion absorption peak at a wavelength of 3.0μm.A 2.94μm Er:YAG laser is used as the pump source to pump a Fe^(2+):ZnSe crystal sample with a size of 10 mm×10 mm×4 mm.When the repetition frequency is 100 Hz,the laser energy output reaches 12 mJ,and the output wavelength tuning range is 3.95~4.15μm.
