Abstract

We derive unidirectional pulse propagation equations to describe extreme high-intensity and ultrabroadband optical interactions in uniaxial crystals, showing both second- and third-order nonlinear optical susceptivities. We focus our attention on the anisotropic nature of the quadratic and cubic nonlinear response of beta-barium-borate (β-BaB2O4, BBO) crystals. Two nonlinearly coupled first-order (in the propagation coordinate) equations describe the dynamics and interactions of the ordinary and extraordinary field polarizations, and are valid for arbitrarily wide pulse bandwidth. We exploit this model to predict harmonic and supercontinuum generation in BBO crystals under the strong and competing influence of quadratic and cubic susceptivities.
