Nanosecond-laser-induced optical wave mixing and ultrasonic wave generation in the nematic phase of liquid crystals.
We have quantitatively observed for the first reported time nanosecond-laser-induced optical wave mixing and ultrasonic wave generation in nematic liquid-crystal films. The effect may prove useful for microsecond wave-front conjugation with a moderate-power laser or gigahertz acousto-optic switching.
