激光主动成像雷达CO2激光器研究
Study on CO2f Laser for Active Imaging Lidar
摘要
介绍了用于激光主动成像雷达的射频激励小型波导CO2激光器(主振激光器和本振激光器)的设计和实验结果.主要实验结果为:主振激光器调Q频率41.67 kHz,脉冲宽度(FWHM)150 ns,峰值功率360 W,本振激光器连续输出功率3.05 W,主振、本振激光器输出激光模式EH11,短期稳频度1.76×10-8,长期稳定P20支输出.
Abstract
An experiment of mini waveguide CO 2 laser including master oscillator and local oscillator, excited by radio frequency (RF) for active imaging lidar is reported in this paper. The following main experimental results have been gotten: 150 ns pulse width (FWHM), 360 W peak power at 41.67 kHz pulse repetition frequency by electrooptical Q switch for master oscillator. 3 05 W CW output for local oscillator. EH 11 mode, long time stable P20 line output with 1 76×10 -8 stability (short time) for this laser.
