Abstract

Efficient second harmonic generation of femtosecond and picosecond pulses into the visible and near-ultraviolet is reported using the quasi-phase-matched nonlinear material, periodically-poled KTP, and the new birefringent nonlinear crystal, BiB₃O₆. Second harmonic average powers as much as 1 W in the blue, tuning throughout 370-450 nm, single-pass conversion efficiencies in excess of 50% and pulse durations from 200 fs to 3 ps have been achieved.
