Remote Sensing Using AgGaSe2 Optical Parametric Oscillator

获取有关大气污染物的有价值信息的理想方法是使用LIDAR.SEO提出了利用调Q Ho：YAG激光器泵浦光学参量振荡器(OPO)用AgGaSe_2非线性晶体作为连续可调输出的增益介质从3微米到12微米。该激光系统将用作激光雷达系统的发射机，用于探测大气污染物。第一阶段将包括开发一个从3微米到12微米可调的OPO系统和一些早期的激光雷达测量。

An ideal method to obtain valuable information on atmospheric pollutants is through the use of LIDAR.SEO proposes in this Phase I to use a Q-switched Ho:YAG laser to pump an Optical Parametric Oscillator (OPO) with AgGaSe2 nonlinear crystal as the gain medium for the generation of continuously tunable output from 3 um to 12 um. This laser system will be used as the transmitter for a LIDAR system to detect atmospheric pollutants. Phase I will consist of developing an OPO system tunable from 3 to 12 um and some prellmlnary LIDAR measurements.
