Abstract

We report a novel tilted pulse amplification technique that, in contrast with the chirped-pulse amplification method, allows stretching of ultrashort pulses independently upon the initial pulse bandwidth. A gain factor of 4.5 and good reconstruction of a $15\mathrm{ps}$ pulse after stretching to $200\mathrm{ps}$ in a double-pass end-pumped Nd:YAG amplifier have been achieved.
