We demonstrate a method that enables accurate timing jitter spectral-density characterization of free-running mode-locked laser oscillators over more than 10 decades of Fourier frequency from mHz to tens of MHz range. The method is based on analyzing both the input voltage noise to the slave laser and the output voltage noise from the balanced optical cross-correlator (BOC), when two mode-locked lasers are synchronized in repetition rate by the BOC. As a demonstration experiment, timing jitter…

Timing jitter reduction through relative intensity noise suppression in high-repetition-rate mode-locked fiber lasers.

The results verify the theoretical prediction that the relative intensity noise (RIN) induced timing jitter by self-steepening effect dominates the jitter performance below ~100 kHz and shows that the effect of RIN decays below ~3 kHz.

Reference-free, high-resolution measurement method of timing jitter spectra of optical frequency combs

The demonstrated method can serve as a simple and powerful characterization tool for timing jitter PSDs of various comb sources including mode-locked oscillators, supercontinua and recently emerging Kerr-frequency combs; the jitter measurement results enabled by the method will provide new insights for understanding and optimizing timing noise in such comb sources.
