Abstract :
Using a 40-fs Ti:sapphire pump laser, we produced 20-fs infrared pulses in a β-barium borate (BaB2O4) optical parametric amplifier without any external dispersion compensation. These results are in good agreement with a novel semi-analytical computer simulation. We also demonstrate that cascading of second-order nonlinear effects yields simultaneous production of ultrashort visible pulses from a near-infrared (NIR) pump
