Abstract

We report a diode-pumped Yb:KYW amplifier delivering up to 27mJ pulses at a repetition rate of 100Hz and a spectral bandwidth of 5.5nm, centered at around 1030nm. The system is based on a double-head multipass amplifier configuration where the pump thermal load is distributed over two relatively thin laser crystals, which permits a sufficiently large number of passes with minimal passive losses, thus maximizing the energy extraction efficiency. The amplified pulse bandwidth theoretically supports 340fs pulses, and as a demonstration, a small fraction of the amplified pulses has been compressed to 560fs.
