We demonstrate that the methodology of frequency-resolved optical gating (FROG) is applicable to time-resolved reflection spectroscopy of a plasma mirror in the vacuum-ultraviolet (VUV) region. A VUV waveform and a time-dependent reflectivity in the VUV region are simultaneously retrieved from a VUV reflection spectrogram of a plasma mirror formed on a fused silica surface by an intense femtosecond laser pulse. The present method enables us to fully characterize a significantly chirped VUV pulse whose duration is as long as 1 ps.
