Abstract: In this paper,we discuss the experimental results of intracavity CdTe electro-optical Q-switch for RF excited waveguide CO2 lasers with frequency-stable and line-selected,which is used in an active imaging radar.The loss of CdTe in the laser has been calculated and the results are consistent with that of experiment.We also discuss the thermal stability of the CdTe crystal and 1/4 waveplate,as well as the pulse characteristic of CdTe Q-switch at various instances.This laser has EH11 output mode with 150ns pulse width(FWHM),360W peak power at 41.67kHz pulse repetition frequency.
