ABSTRACT:
For the acquisition of data for determining the duration and chirp (frequency modulation) of a single ultrashort laser radiation pulse said pulse is split into two partial pulses which are each conducted through one of two TREACY compressors having different group delay dispersions and then recorded in succession on the same time basis with a streak camera.
