Paper Abstract

A powerful pump in a nonlinear medium can affect a weak probe beam propagating through a medium. In these induced effects there is not an exchange of power or a shifting of wavelengths, as seen in parametric effects, but instead the index of refraction, (Delta) n, brought about by the pump affects the propagation of the probe. The weak probe can be steered, guided, shaped or focused due to the influence of the pump beam. All of these effects fall under the general heading of cross phase modulation. This work presents a primary set of experiments demonstrating a nonlinear optical effect which displays a saturation profile. The nonlinear media is zinc selenide that is cut to be 3 X 3 X 25 mm with all sides polished. The probe is a continuous wave HeNe laser operating at 632.8 nm. The pump is a single mode, linearly polarized beam from an Argon laser with a center wavelength of 500 nm.
