Selective intracavity control of interlaced femtosecond soliton combs — •Julia A. Lang1, Luca Nimmesgern1, Sarah R. Hutter2, Alfred Leitenstorfer2, and Georg Herink1 — 1Universität Bayreuth, Deutschland — 2Universität Konstanz, Deutschland
Complex sequences of multiple solitons are observed in almost all ultrafast mode-locked laser, but their dynamics remain difficult to access, control, or eventually apply. In this contribution, we present deterministic control of relative soliton motion between two interlaced harmonic mode-locked frequency combs. We implement intra-cavity control by acousto-optic modulation allowing us to selectively address pulses in a 40 MHz Er:fiber laser. The soliton trajectories following the external stimulus are rapid, tuneable and deterministic. As shown in [1], intracavity feedback plays an important role in the formation of stable soliton molecules. In this work, we experimentally resolve and analyse the dynamics in the frame of soliton interaction with an effective binding potential. As a proof-of-concept, we demonstrate first steps towards the use of tuneable intracavity soliton motions for ultrafast pump-probe spectroscopy.
