Abstract

Using a novel (to our knowledge) broadband Yb-doped Yb3+,Na+:CaF2 crystal cooled in a closed loop to 130K we demonstrate a chirped pulse regenerative laser amplifier delivering the energy of up to 3mJ at a repetition rate of 1kHz and an average output power of 6W at 20kHz. The gain narrowing in the laser crystal is compensated by shaping the amplitude of the seed pulse spectrum. As the result, at the highest amplified pulse energy we obtain a 12nm FWHM bandwidth supporting a 130fs pulse duration, assuming ideal compression. Amplified pulses were recompressed from 250psto195fs with a 1700  linesmm transmission grating compressor.
