Abstract
In this paper we discuss enhancement techniques for use with BSO and Ga As. These techniques include application of electric fields both a.c. and d.c. We consider the effects of crystal orientation and of beam polarisation and present results for two wave mixing in BSO and Ga As. For Ga As results we propose absorption gratings to fully explain our results. We show that the 43m structure of Ga As makes,it ideally suited for a four-wave mixing configuration with positive feedback.
