Paper Abstract

Using Fresnel phase retrieval method for two intensity profiles, we first construct the phase-map of the HeNe laser beam in a specially built optical system. After validating this result with the analytical value we proceeded to the nonlinear three-wave interaction. The Fresnel technique is once again employed to obtain the phase map of the input pump and signal beam. The phase information of these input beams are then used in a two-dimensional numerical model we have developed for three-wave nonlinear interactions. The outcome from the numerical model is then compared to the phase map of the output pump and signal beam.
