Abstract

We present the results of our theoretical and experimental investigation of the pulsed heterodyne of an electro-optically Q-switched radio-frequency-excited CO2 waveguide laser with two channels. We used a six-temperature model for CO2 lasers to describe the process of dynamic emission in an electro-optically Q-switched laser. The calculated pulse waveforms are in good agreement with the experiment, which we used as the basis for our theoretical study of a pulsed laser heterodyne and its Fourier transform frequency spectrum. The experimental results are consistent with the theoretical analyses.
