We developed liquid-jet plasma-mirror frequency resolved optical gating (PM-FROG) technique. The spectra of the second harmonic pulses reflected by plasma-mirror generated by focusing the fundamental pulses onto liquid-jet surface were recorded as a function of the time-delay. The waveform of the second harmonic including the phase could be retrieved from the measured PM-FROG trace. In addition, we calculated the time-evolution of a reflectivity of the plasma mirror based on the Drude model.
