Abstract: The specific features of experimental implementation of a cross-correlator with a scan rate above 1600 cm s^-1 and a spatial delay amplitude of more than 15 mm are considered. The possibility of measuring the width of femtosecond pulses propagating in a train 300 μs in duration with a repetition rate of 1 MHz is demonstrated. A time resolution of 300 fs for the maximum time window of 50 ps is attained. The cross-correlator is aimed at testing 3D pulses of a laser driver of an electron photo-injector.

Keywords: cross-correlator, pulse temporal profile.
