Abstract

An instantaneous modulation bandwidth of 1 GHz and a mechanically tunable bandwidth of 3 GHz with an efficiency of 27% has been obtained for the output frequency of a CO 2 laserusing the linear electro-optic effect in single crystal CdTe. The microwave (modulating) field is applied on a pulsed basis to reduce crystal damage due to heating. A CW efficiency of 0.15% was obtained. By choosing a particular crystal orientation 90% efficiency was obtained on a pulsed basis.
