Paper Abstract

A non paraxial formulation of non linear optical mixing is presented. The method is based on the angular spectrum representation of the interacting waves and it considers depletion effects for copropagating beams. Applications for far infrared generation by three wave mixing are made. Photon conversion efficiency, its angular distribution, and the influence of walkoff and frequency of the pumping beams are studied. We have compared the results with those of the parametric and paraxial approximations.
