Complete removal of Gordon-Haus jitter in large dispersion femtosecond fiber lasers

Timing jitter optimization of mode-locked lasers is essential for applications that require high temporal resolution. In this work, both numerical simulation and experiments show that the Gordon-Haus timing jitter of large-net-dispersion mode-locked fiber lasers can be removed with an intra-cavity narrow band-pass filter. As a result, the filtered lasers exhibit rather low timing jitter that is immune to the net dispersion variation. Such scheme is simple and robust, which provides an alternative for long-term stabilization and timing jitter reduction of mode-locked fiber lasers.
