Modeling Nonlinear Optical Processes in a Periodically Poled Nonlinear Crystal

详细

Three nondegenerate processes are considered: the parametric and simultaneous generation of sum frequencies in a periodically poled nonlinear crystal. The behavior of the average number of photons of interacting modes and their mutual correlations of orders 3, 4, and 5 are studied numerically. A new effect of inversion of the mutual correlation of the modes of the generated radiation is observed at certain length of interaction.
