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.
