Contra-Directional Two-Beam Coupling for Variable Rear Reflectivities in LiNbO3:Fe (Preprint)

Abstract

1. Coating the rear c-surface, we are able to produce a controlled range of rear reflectivity on a photorefractive LiNb03 crystal. 2. The contra-directional two-beam coupling does not vary significantly with reduced rear reflection. This agrees with theoretical calculation. 3. The time response of two beam coupling increases with reduced reflectivity. 4. Future work will produce similar work on other types of photorefractive crystals.
