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 crystal in both stages and pumped at by a Ti:sapphire laser amplifier, provides sub- signal pulses across the whole tuning range of with minimum duration of and maximum signal energy of .
