Abstract: We report a series of experimental results showing that the acceptance bandwidth of second harmonic generation in quadratic crystals may substantially broaden when using pumps at high intensities. We highlight the co-existence of second harmonic generation and strong unconventional spatial beam reshaping. Our experimental results are in good agreement with our numerical simulations.
