A single-shot transient-grating frequency-resolved optical gating (TG-FROG) device was set up to measure UV ultrashort pulse laser with pulse duration within 10ps.The performance of the device was demonstrated by experimental data measured on discharge-pumped KrF laser which is operated in 10Hz repeated frequency mode,and on electronbeam- pumped KrF laser which is only operated in single-shot mode.For the former,the TG-FROG can distinguish the changes of the pulse shape,spectrum and phase when the pulse chirp is changed.For the later,the TG-FROG finds that the pulse shape has multiple peaks whose pulse duration is about 2ps,and the spectrum is modulated whose bandwidth is about 1.3nm,and the corresponding phases present parabolic structure.
