Abstract

We report on a compact and simple system delivering pulses as short as 60fs with an energy up to 330μJ at 2kHz and 200μJ at 5kHz. High energy pulses delivered by a diode-pumped ultrafast laser with 500fs pulse duration are injected in a hollow fiber filled with nitrogen, experiencing spectral broadening through self-phase modulation, and are subsequently compressed to sub-100fs pulse duration using negative dispersion mirrors. The overall power efficiency of 40% and the temporal compression factor larger than 8 leads to a peak power increase of more than 3, corresponding to 5GW peak power in the multi-kilohertz regime.
