We experimentally identify that narrow bandpass-filtering can significantly reduce the timing jitter in normal-dispersion fiber lasers. Both the split-step method-based jitter simulation and the modified Namiki-Haus analytic model agree well with the measured jitter spectrum.
We demonstrate 14.3-attosecond timing jitter [integrated from 10 kHz to 94 MHz offset frequency] optical pulse trains from 188-MHz repetition-rate mode-locked Yb-fiber lasers. In order to minimize the timing jitter, we shorten the non-gain fiber length to shorten the pulsewidth and reduce excessive higher-order nonlinearity and nonlinear chirp in the fiber laser. The measured jitter spectrum is limited...
We demonstrate 18-attosecond timing jitter [10 kHz–94 MHz] pulse trains from 188MHz mode-locked Yb-fiber lasers. This is the lowest timing jitter from free-running fiber lasers, comparable to the performance of lowest-jitter Ti:sapphire lasers.
