Abstract

Recent theoretical and experimental results have shown that the orientational photorefractive effect seen in doped nematic liquid crystal films gives rise to strong beam amplification effects without suffering from phase crosstalk. These effects, examined for both four and two wave mixing, are well suited for adaptive optics applications.
