The cases of light beams confined in one and two dimensions have been examined. The orientational instability threshold and the jump of a director deviation angle at the transition, as well as their dependences on the transverse size of the incident light beam, were found in the regimes of incident light intensity growth and reduction. Conditions, under which the width of the hysteresis loop is maximal, have been determined. |
