We report a dispersion compensated 1-GHz femtosecond optical parametric oscillator synchronously pumped by a 76-MHz Ti:sapphire laser using a cavity longer than the fundamental synchronous cavity length with improved output power and near-transform-limit pulses.
Broadly tunable picosecond pulses from the ultraviolet to infrared (370-2497 nm) have been obtained by optical parametric generation and amplification in BiB3O6. Pulse energies of 48.6 muj at conversion efficiencies as high as 30% have been generated.
Power scaling to >1 mJ is demonstrated for a tunable (1.1-2.9 mum) femtosecond (<140 fs) optical parametric amplifier based on the monoclinic crystal BiB3O6, pumped near 800 nm by a 1 kHz Ti:sapphire laser amplifier.
