High-efficiency energy transfer due to stimulated orientational scattering of light in nematic liquid crystals
Nelson V. Tabiryan, Andrey V. Sukhov, Boris Ya Zel'dovich
The saturation stage of stimulated orientational scattering (SOS) of light in thick planarly aligned nematic-liquid-crystal layers was observed and studied experimentally. The power efficiency of o-wave pump conversion exceeded 90%. Both saturation of transmitted pump power and cascading of SOS were observed. The latter indicated that, for higher than ∼50% conversion efficiencies, inverse conversion of the scattered e-polarized signal into wide-angle speckle, o-polarized background started to take place, leading to partial depletion of the primarily scattered e wave. Results were in good qualitative agreement with conventional SOS theory.
