Abstract
A general geometric condition, involving group velocities, for large b andwidth parametric amplification with all types of phase-matching and in certain wavelength ranges is derived. This condition has been expl oited to produce visible widely tunable sub-20-fs pulses from an optic al parametric oscillator and an optical parametric amplifier based on beta-barium berate pumped in the blue. These results are interpreted i n terms of a modified soliton model for the optical parametric oscilla tor (OPO) and detailed numerical simulations for both devices.
