Zero focusing via competing nonlinearities in beta-barium-borate crystals

Abstract : We investigate nonlinear focusing behavior of light beams propagating in beta-barium-borate crystals under mis- matched second-harmonic generation. We clearly identify experimentally multiple self-focusing and defocusing regions against the orientation angle and the condition where competing quadratic and cubic nonlinearities per- fectly compensate each other (zero-focusing point).
