When amplifying multiple ultrashort pulses at once utilizing the chirped-pulse amplification (CPA) technique, several technical challenges need to be considered. In our paper recently published in Optics Express, we investigate the effects of nonlinearities in multi-pulse CPA with picosecond pulse spacings. Primarily at higher multi-millijoule energies, it is shown that nonlinearities result in the formation of parasitic pre- and post satellite pulses under the given circumstances. Numerically and experimentally, we demonstrate successful suppression of the mentioned satellites and discuss strategies to avoid degradation of the amplified multi-pulse waveform due to nonlinear effects.
