本文介绍了一种基于取向图案化砷化镓的脉冲单频可调谐光参量振荡器的工作。由于晶体温度调谐，该源覆盖10.2-11.2和7.6-8.6 $$upmu hbox {m}$$μm范围内的单纵模操作与线宽低于30 MHz。通过在集成路径差分吸收激光雷达（IP-DIAL）设置中实现该源，对10.35和10.5 μm附近的氨进行了稳态检测。
This paper presents our work on a pulsed single-frequency tunable optical parametric oscillator based on orientation-patterned gallium arsenide. Owing to crystal temperature tuning, this source covers the 10.2–11.2 and 7.6–8.6 $$upmu hbox {m}$$μm ranges in single-longitudinal mode operation with a linewidth below 30 MHz. Standoff detection of ammonia around 10.35 and 10.5 $$upmu hbox {m}$$μm is performed by implementing this source in an Integrated Path Differential Absorption Lidar (IP-DIAL) setup.
