Tunable pulse-width, electro-optically cavity-dumped, rf-excited Z-fold waveguide CO2 laser

In this paper, an electro-optically cavity-dumped, rf-excited, Z-folded waveguide CO2 laser is presented. Theoretical studies on the laser output wave form and method to control laser pulse width and output power are made. In the experiment, a pulse width of a cavity-dumped laser can be changed from 12 to 32 ns. However, the corresponding peak powers reduce from 7000to2800W at a pulse repetition rate of 10kHz. The experimental results are consistent with the theoretical analyses.
