Beam combining using Orientational Stimulated Scattering in Liquid Crystals

摘要

Possibility of beam combining and clean-up using Orientational StimulatedScattering in a Nematic Liquid Crystal is considered. We numerically study thedynamics of the process and find that back-conversion process tends to limitthe effective interaction strength. Instability of the steady state ofcross-phase modulation is demonstrated, when both waves have the samefrequency. We show that high conversion efficiency can be achieved, and thatthe shape and wave-front of the amplified output signal are robust with respectto amplitude and phase distortions of the input pump.
