Abstract

The indirect measurement method of the temporal profile and spectrum of Femtosecond Laser Pulses (FLP) carried out by the multi-beam cross-correlator is described. The method of temporal scaling of the single-shot irreproducible FLP under investigation was applied by scanning of the broadened FLP spectrum by pulses of a given shape at various wavelengths in a non-linear crystal. As a result of such an interaction a dynamic spectrogram is formed at the output of the non-linear crystal, from which the temporal profile and spectrum of the investigating FLP is defined.
