Free‐Running Single‐Cavity Dual Combs With Hz‐Level Relative Linewidth

ABSTRACT Single‐cavity dual‐comb lasers provide a compact and efficient source for dual‐comb spectroscopy in gas sensing applications; however, achieving sufficient free‐running mutual coherence for comb‐line‐resolved, high‐resolution measurements remains challenging. Here, we pr...
