Broadband high energy diode pumped Yb:KYW multipass amplifier

Résumé

We report a diode pumped Yb:KYW amplifier delivering up to 27 mJ pulses at a repetition rate of 100 Hz and a spectral bandwidth of 5.5 nm, centered at around 1030 nm. 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 340 fs pulses and as a demonstration, a small fraction of the amplified pulses has been compressed to 560 fs.
