A Study of pulse heterodyne of Z-Fold waveguide CO2 laser


Pulse heterodyne of electrooptically Q-switched RF excited Z-fold waveguide CO2 laser with two channels (partial Z-fold channel and single channel) and common electrodes are presented. The Heterodyne waveform of the pulsed laser and the CW laser are compared to pulse waveform of Q-switched laser. CW laser output has been obtained from the single channel. Pulse width is 140 ns, the delay 300 ns and the peak power 300W. The largest tunable range of heterodyne frequency is 150 MHz and the width of the voltage pulse on the crystal is about 1.2μs.
