DOI: 10.1109/jlt.2022.3152154

Abstract: We demonstrate experimentally that random phase modulation of an erbium-doped fiber ring-laser by an intra-cavity electro-optic phase modulator did not inhibit ultra-short pulse operation (so-called mode-locking). Stable and self-starting operation was achieved even when the… read more here.
