| Abstract: | Discontinuities and hysteresis have been observed when controlling the orientation state of a nematic liquid crystal (NLC) with a single laser beam in standard geometry: the light beam of extraordinary polarization interacts with a homogeneously oriented NLC. In a certain range of control parameters (light intensity and incidence angle), the system exhibits a new phenomenon of nonlinear dynamics. |
