Abstract
A single-shot phase-sensitive autocorrelator for the investigation of high-intensity ultraviolet laser pulses is developed and tested. The fluorescence of the two-photon-excited self-trapped excitons in BaF2 is used as a nonlinear detector. Simultaneous measurements of the temporal phase structure and the spectrum of a subpicosecond KrF laser are reported.
