Abstract
We report the generation of tunable femtosecond pulses in the near-IR using a two-stage, white-light seeded, collinear, femtosecond optical parametric amplifier (OPA). The OPA, based on BiB(3)O(6) crystal in both stages and pumped at 800 nm by a 1 kHz Ti:sapphire laser amplifier, provides sub-30 fs signal pulses across the whole tuning range of 1.15-1.6 microm with minimum duration of 22 fs and maximum signal energy of 80 microJ.
