Abstract:

The influence of various factors on stability of the performance data of compact CO2 waveguide lasers (the LCD series) produced by Plazma JSC in 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 the 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 the 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 the 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 monitoring of the environment.
