Intra-Cavity Control of Dual-Comb Soliton Motion inside a single Fiber Laser — •Julia A.

Ultrafast lasers can exhibit dynamic sequences of multiple solitons. However, understanding and controlling their dynamics or utilizing them practically remains challenging. In this contribution, we introduce a new method for the precise control of relative soliton motion. By employing intra-cavity acousto-optic modulation, we selectively modulate single pulses out of two interlaced harmonically mode-locked frequency combs in an all-fiber Er:fiber laser. Upon external stimuli, the trajectories exhibit rapid and deterministically adjustable behaviour as a result of the interplay of ultrafast nonlinearity and laser gain dynamics. Based on these findings, we demonstrate fast all-optical scanning of picosecond pump-probe delays and programmable free-form soliton trajectories [1].
