Abstract

We consider non-degenerate two-wave mixing in photorefractive Bi12SiO20. It is shown theoretically that the presence of absorption and optical activity in the photorefractive media may result in a number of maxima for the gain as the frequency detuning between the two beams is varied. Further, when the beam interaction is used for optical amplification, there may also exist an optimum crystal length beyond which there is a reduction in the useful gain obtainable. Experimental results are presented in confirmation of the theory.

Uncontrolled Keywords: non-degenerate two-wave mixing, photorefractive Bi12SiO20, absorption, optical activity, frequency detuning, beam interaction, optical amplification
