Frequency resolved optical gating (FROG) is a popular method for complete characterization of laser pulses. In FROG, a reconstruction algorithm retrieves the pulse from its measured auto-spectrogram (FROG trace). We propose and demonstrate, numerically and experimentally, multiplexed FROG in which several pulses of a pulse–burst are retrieved simultaneously from a single measured trace, which corresponds to the incoherent sum of the FROG traces of the individual pulses. Implementing multiplexed FROG in GRENOUILLE (single-shot FROG) can enable characterization of pulses in non-repetitive pulse-bursts that are currently not measurable.
