Abstract

We describe the observation of a new phenomenon: the cancellation of molecular reorientation that has been achieved in nematic liquid crystals acted on by two competing (pulsed) light beams. The effect is unstable: Starting from the cancellation condition, we have observed patterns related to the presence of a nonlinear phase shift in both beams when their intensity was increased simultaneously. We characterize the behavior of the induced phase shift as a function of the impinging power.
