Abstract

Abstract: A novel coherent pulse control technique that actively exploits the high controllability of multi-comb systems is proposed. We generalize the frequency relationships between comb sources and utilize the relative carrier envelope phase controllability through the relative offset frequency, Δ f ceo, of the combs. To show the utility of this concept, we demonstrate polarization-modulated comb generation and its coherent detection. This experiment corresponds to an extended dual-comb spectroscopy, in which effective triple-combs are involved in total. Our successful proof-of-principle experiment exhibits the excellent potential of the multi-comb systems, achieving rapid, precise, and arbitrary coherent control in broad metrological applications.
