Abstract

The influence of various factors on the stability of the performance parameters of compact CO₂ waveguide lasers (the LCD series) produced by Plazma JSC (Russia) has been considered for the first time. An angular misalignment of cavity mirrors was found to be the main reason for the relative instability of laser emission in the frequency range of 0–0.5 Hz. These lasers work under RF excitation and have a power output from 3 to 50 W in a non-selective oscillating mode. Lasers can work at a fixed emission wavelength or in the wavelength-change mode. Preprogrammed dynamic control of the laser's emission spectrum can be carried out in the automatic mode using the built-in servo driver from a personal computer. The CO₂ waveguide lasers of the LCD series can be used in laser lidar systems, particularly, for observation of small-sized objects and environmental monitoring.

LCD系列波导激光器及其应用的一些特点

本文首次考虑了各种因素对俄罗斯Plazma公司生产的紧凑型CO2波导激光器(LCD系列)性能参数稳定性的影响。在0 ~ 0.5 Hz范围内，腔镜的角度失调是导致激光发射相对不稳定的主要原因。这些激光器在射频激励下工作，在非选择性振荡模式下具有3至50 W的功率输出。激光器可以在固定的发射波长下工作，也可以在波长变化模式下工作。激光发射光谱的预编程动态控制可以在自动模式下使用内置的伺服驱动器从个人计算机进行。LCD系列CO2波导激光器可用于激光激光雷达系统，特别是用于观察小型物体和环境监测。
