    Abstract

    We modify the well-known photothermal beam deflection technique to study ultrafast nonlinearities. Using phase-sensitive detection we directly measure the temporal and polarization dynamics of nonlinear refraction (NLR) with sensitivity to optically induced phase changes of approximately lambda/20, 000. We use the relative polarization dependence of excitation and probe to separate the isotropic and reorientational components of the NLR. (C) 2013 Optical Society of America
