| Abstract: | We present experimental results concerning the polarisation optical bistability in the B5NH4 crystal together with an attempt of its theoretical explanation based on third-order optical nonlinearity and Fresnel's boundary conditions. In our experiments a strong laser beam is transmitted through a crystal plate of B5NH4. The polarisation state of the transmitted light depends in a bistable way on the intensity of the incident light. |
