Abstract

A general geometric condition, involving group velocities, for large bandwidth parametric amplification with all types of phase-matching and in certain wavelength ranges is derived. This condition has been exploited to produce visible widely tunable sub-20-fs pulses from an optical parametric oscillator and an optical parametric amplifier based on β-barium borate (BaB₂O₄) pumped in the blue. These results are interpreted in terms of a modified soliton model for the optical parametric oscillator (OPO) and detailed numerical simulations for both devices
