摘要

摘要:
为了获得可调谐长波红外输出，本文设计了一种基于ZnGeP₂（ZGP）温度调谐的长波红外光参量振荡器。采用中心波长为2097 nm的Ho:YAG 器泵浦不同相位匹配角的ZGP晶体，通过改变晶体工作温度来研究ZnGeP₂光参量振荡器(ZGP-OPO)的温度调谐特性。在15~30 °C温度范围内，实现了7.53~8.77 μm分段可调谐长波输出，总调谐宽度为1.24 μm。整个调谐范围内，输出功率大于1.503 W，当闲频光波长为8.77 μm时，输出功率为1.503 W，斜率效率和光光转换效率分别为12.19%和6.53%。实验结果表明，ZGP温度调谐是实现连续可调谐长波红外输出的有效技术途径。本实验研究在可调谐长波固体器工程化领域具有潜在的应用价值。

Abstract:
In order to realize tunable longwave infrared laser, we design a ZGP temperature tuned longwave infrared optical parametric oscillator. A Ho:YAG laser with the center wavelength of 2097 nm is used to pump ZGP crystals with different phase matching angles. The temperature adjustable properties of ZGP-OPO is researched by changing the operating temperature of crystal. The laser with a segment continuously tunable range of 7.53−8.77 μm is realized in the temperature range of 15−30°C, with a total tuning range of 1.24 μm. The output power of ZnGeP₂-Optical Parametric Oscillator(ZGP-OPO) is greater than 1.503 W over the entire tuning range. The output power is 1.503 W at the idler wavelength of 8.77 μm, and the corresponding slope efficiency and optical conversion efficiency are 12.19% and 6.53%, respectively. The experimental results show that temperature tuning of ZGP is an effective technical method to obtain continuously tunable long-wave infrared laser. This research has potential application value in the field of engineering of tunable long-wave laser.
