Abstract
Results from a transient simulation of vector wave propagation anisotropic crystals are presented and compared with those of other authors and with analytical calculations. The results verify aspects of the simulation over 10 orders of magnitude in intensity and pulse duration. Several materials have been used in the validation, including GaAs, BaTiO43, and BSO. The model uses nonlinear zero-order equations for the evolution of the medium, and linearized first-order equations. The zero-order behavior is set by the mean optical intensity; the transverse variations of the optical intensity the treated as first-order perturbations using well-·known split-operator techniques. Multiple physical effects, e.g., photorefractivity, the Franz-Keldysh, free-carrier, and thermal effects are included in the model, and have been tested individually.
