Abstract

A novel time-resolved nonlinear spectroscopic technique is described, which is based on stroboscopic registration of optical polarization transformation taking place at a vector incoherent two-wave mixing interaction in a modified Mach-Zehnder interferometer. It allows an accurate measuring of the dynamics of excitation and relaxation for real and imaginary parts of complex nonlinearity tensor components. The technique is demonstrated for measuring the light-induced change of transient absorption (delta) (alpha) _e(t), (delta) (alpha) _o(t) and refraction (delta) n_e(t), (delta) n_o(t) for bacteriorhodopsin- based film pumped by linearly polarized laser pulses.
