Abstract:

We describe and measure the effects of self-defocusing on the various coupling effects produced when two coherent, noncollinear, picosecond optical pulses strong excitation and weak probe are both spatially and temporally coincident in a thin silicon wafer. Specifically, we observe that the weak probe beam experiences considerably more defocusing than the excitation beam. We believe that this is the first direct confirmation of weak-wave retardation in light-by-light scattering experiments. We also observe the effects of this defocusing on the quality of the forward traveling conjugate wave.
