Abstract

Intensity-dependent polarization rotation that results from the simultaneous action of two third-order processes, self-phase modulation and four-wave mixing, is observed. The effect is recorded along the fourfold axis of a ${\mathrm{YVO}}_4$ crystal. The angle of rotation is proportional to the square of the input intensity–crystal length product. This is to the authors’ knowledge the first experimental evidence showing that intensity-dependent polarization rotation can be related to the real part of cubic susceptibility.
