Photorefraction as a Diagnostic Tool for InP.

Abstract:

The phase shift between the intensity pattern and the index pattern in two-wave mixing experiments has been determined from measured values of photorefractive two-wave mixing gain and diffraction efficiency in a bulk InPFe crystal as a function of the total incident intensity. Remarkably, the phase shift varies from 0 to 180 degrees with a value of 90 degrees at the intensity for which the two-wave mixing gain peaks Comparison between theory and experiment yields values for sample Fe2 and Fe3connections at 6 x 10exp 15cu cm and 4.8 x 10exp 16cu cm respectively.
