Abstract

We investigate numerically how to control and reduce power-dependent walk-off by using a three-dimensional model for beam propagation in highly nonlocal bias-free nematic liquid crystals (NLCs). We consider beam propagation with different initial momenta and rest angles. Owing to the highly nonlocal character of the dielectric response of NLC, we demonstrate various beam trajectories. We show that it is possible to practically eliminate walk-off in real NLCs by properly choosing the angle of incidence.
