We demonstrate sub- 100 - as timing jitter optical pulse trains generated from free-running, 77.6 MHz repetition-rate, mode-locked Er-fiber lasers. At 0.002 ( ± 0.001 ) ps 2 net cavity dispersion, the rms timing jitter is 70 as ( 224 as ) integrated from 10 kHz ( 1 kHz ) to 38.8 MHz offset frequency, when measured by a 24 as resolution balanced optical cross correlator. To our knowledge, this result corresponds to the lowest rms timing jitter measured from any mode-locked fiber lasers so far. The measured result also agrees fairly well with the Namiki–Haus analytic model of quantum-limited timing jitter in stretched-pulse fiber lasers.
