Abstract

Lidar measurements of atmospheric gases in the spectral ranges 1.8–2.5 and 3–4 μm have been numerically simulated. The differential absorption lidar system based on optical parametric oscillators with nonlinear KTA and KTP crystals is described; it allows tuning laser radiation in the near/mid-IR wavelength regions. Lidar echoes have been experimentally recorded in the 1.8–2.5 and 3–4 μm wavelength ranges.

近/中红外OPO激光雷达系统用于大气气体分析：模拟和测量结果

摘要

已经对数值范围为1.8–2.5和3-4μm的光谱范围内的大气气体的激光雷达测量进行了模拟。描述了基于具有非线性KTA和KTP晶体的光学参量振荡器的差分吸收激光雷达系统；它允许在近/中红外波长范围内调谐激光辐射。激光雷达回波已经在1.8–2.5和3–4μm波长范围内进行了实验记录。
