Abstract :
[en] We report on suppression of supermode noise in harmonically mode-locked fiber laser achieved through the injection of continuous wave (CW) into the laser cavity. Implementing this method, we have shown experimentally that supermode suppression level of harmonically mode-locked laser could be increased by 20-30 dB depending on the pulse energy of the mode-locked laser. Experiments have refined the requirements to the positions inside the laser spectrum assigned to the injected CW component, a Kelly soliton sideband, and the transparency peaks of the birefringent filter formed in the ring fiber cavity. The effect takes places at proximity of the injected CW to the Kelly sideband leading to phase-locking between the CW and the solitons.
