Laser-Induced Optical Nonlinearities In Ferronematics

Nematic and ferronematic samples were subjected to high power laser irradiation. Optical nonlinearities such as diffraction rings and self focussing effects were examined as function of light intensity. It is shown that the self-focusing effect appearing in a ferronematic(obtained by dispersing 0.1%yttrium iron garnet into nematic 4799 Merck)is smaller when compared to that encountered in pure nematic. A theoretical approach was elaborated to explain these optical nonlinearities in ferronematics and good agreement with the experimental findings was found.
