Abstract

An electro-optically Q-switched partial Z-folded RF CO_{2} waveguide laser with an intracavity CdTe modulator has been designed and characterized. The partial Z-fold channel is 3*460 mm in length. In this paper we study the laser output power as a function of gas pressure for partial Z-fold channel without Q-switched crystal inside the cavity. The maximum laser output power is about 21 W. For Q-switch operation, the peak power is 730 W and the pulse width is 150 ns.
