Strong beam coupling was observed in mesogenic materials consisting of low- and high-molar-mass liquidcrystal mixtures with high concentration ratios of the latter type of liquid crystal. The beam-coupling effects originate in orientational photorefractive Bragg gratings, and a weak signal beam with an intensity of 1 mW is amplif ied to 8 mW by energy exchange with a strong pump beam after the passage of a 50-μm-thick film under a low operating voltage of 1–4 V/ μm. There is a superior net two-beam coupling gain of more than 600 cm-1 with the low operating voltage and high resolution.
