Abstract

We report efficient 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 BiB3O6 crystal in both stages and pumped at 807nm by a 1kHz Ti:sapphire laser amplifier, provides sub-30fs signal pulses after compression with energies exceeding 200μJ, which corresponds to fivefold pulse shortening and 30% internal conversion efficiency in the second stage considering 150fs pump pulses with 1.5mJ energy. The corresponding idler pulses with more than 100μJ have sub-60fs duration without compression. The first stage alone is capable of producing sub-20fs pulses near 1400nm at the microjoule level without using any compression.
