Type II phase-matched {beta}-barium borate is used in the first stage of amplification of a white-light continuum in a two-stage optical parametric amplifier pumped by the second harmonic of a regeneratively amplified Ti:sapphire laser system operating at 824 nm. Near-transform-limited sub-190-fs pulses with microjoule energies are achieved in the signal branch, which is tunable from 475 nm to degeneracy. This system effectively bridges the wavelength gap between the fundamental and the second harmonic of amplified Ti:sapphire laser systems. {copyright} 1995 Optical Society of America
