Abstract

We present what is to our knowledge the first experimental observation of the specular nonlinear anisotropic polarization effect of a pump-induced polarization-plane rotation for normal-incidence reflection from the (001) surface of a cubic crystal. In GaAs, azimuth rotation of the order of 9 × 10-6 rad is seen for a pump intensity of 75 MW/cm2 at 750 nm, from which the anisotropic component of the cubic nonlinearity |Re(χxxxx - 2χxxyy - χxyyx)| = 5 × 10-9 esu is found.
