The fiber single-cavity dual-comb laser (SCDCL) is an emerging light-source architecture that opens up the possibility for low-complexity pump-probe measurements. However, fundamental trade-off between measurement speed and time resolution remains a hurdle widespread use of SCDCLs in In this paper, we break by devising all-optical dynamic repetition rate difference (Δ f rep ) modulation technique.
