Full characterization of an ultrahigh-repetition-rate train of ultrashort pulses generated with phase-coherent Raman sidebands

We generate a train of highly-stable ultrashort-pulses with a repetition-rate of 10.6 THz by synthesizing phase-coherent rotational-Raman-sidebands in para-hydrogen. We show full characterization of its temporal waveform based on a frequency-resolved-optical-gating method.
