Multiplexed FROG |
Abstract: |
Frequency Resolved Optical Gating (FROG) is a popular method for complete characterization of optical laser pulses. In FROG, a reconstruction algorithm retrieves the pulse from its measured auto-spectrogram (FROG trace). We proposed and demonstrate, numerically and experimentally, multiplexed FROG, which characterizes several pulses from a single multiplexed FROG trace (a multiplexed FROG trace corresponds to a sum of FROG traces, where each FROG trace corresponds to one of the pulses in the burst). Multiplexed FROG can characterize isolated burst of pulses that are currently not measurable. |
