摘　　要：采用改进的垂直布里奇曼法在自制的三温区炉内生长出尺寸达Ф24 mm×70 mm的磷锗锌（ZnGeP2,ZGP）单晶体,将晶体在600℃下于同成分粉末包裹中进行了500 h退火热处理。采用X射线衍射仪（XRD）、X射线荧光仪（XRF）以及傅里叶红外光谱仪（FTIR）对ZGP晶体结构、成分和光学性能进行了测试和分析表征。加工制作出ZGP光参量振荡器（ZGP-OPO）,采用2.1μm、7 kHz激光泵浦ZGP-OPO,实现了3~5μm中红外调谐激光输出,功率达0.48 W。上述结果表明所研制的ZGP晶体结构完整,品质高,能够用于制作非线性光学元器件应用。ZnGeP2（ZGP） single crystal with size of 24 mm in diameter and 70 mm in length was grown by a modified vertical Bridgman（VB） method in a three-zone furnace. The crystal was annealed in Zn Ge P2 powder at 600 ℃ for 500 h. X-ray diffraction（XRD）, X-ray fluorescence（XRF） and Fourier transform infrared spectrophotometry（FTIR） were employed to characterize its properties. A ZGP optical parametric oscillator（ZGP-OPO） device was fabricated from the annealed sample. Laser experiment was carried out on the device. Tunable mid-infrared laser in the range of 3~5 μm was realized on the ZGP-OPO pumped by 2.1 μm, 7 k Hz laser. All the results indicate that our grown crystal is in good quality and can be used for nonlinear optical applications.
