摘要

Abstract

Dual-comb spectroscopy (DCS) with few-GHz tooth spacing that provides a better trade-off between spectral resolution and refresh rate is a powerful tool for measuring and analyzing rapidly evolving transient events. Despite such an exciting opportunity

existing technologies compromise either the spectral resolution or refresh rate

leaving few-GHz DCS with robust design largely unmet for frontier applications. In this work

we demonstrate a novel GHz DCS by exploring the multimode interference-mediated spectral filtering effect in an all-fiber ultrashort cavity configuration. The GHz single-cavity all-fiber dual-comb source is seeded by a dual-wavelength mode-locked fiber laser operating at fundamental repetition rates of about 1.0 GHz differing by 148 kHz

which has an excellent stability in the free-running state that the Allan deviation is only 101.7 mHz for an average time of 1 s. Thanks to the large repetition rate difference between the asynchronous dichromatic pulse trains

the GHz DCS enables a refresh time as short as 6.75 μs

making it promising for studying nonrepeatable transient phenomena in real time. To this end

the practicality of the present GHz DCS is validated by successfully capturing the 'shock waves' of balloon and firecracker explosions outdoors. This GHz single-cavity all-fiber dual-comb system promises a noteworthy improvement in acquisition speed and reliability without sacrificing measurement accuracy

anticipated as a practical tool for high-speed applications.
