Abstract

A multiple pulses chirped pulse amplification (MPCPA) laser system was developed. The system can be used for multiple pulses generation in collinear pump probe experiments. In order to generate the multiple pulses, a simple passive pulse shaping technique in the spectral domain is implemented. The ratio of the intensity of the pulses and the delay between them can be controlled. Two and three spectrally separated pulses with duration of 300 fs and energies in the mJ range were generated, with intensity ratios from 0.05 to 1 and delays up to 600 ps..
