Broadband photon-counting dual-comb spectroscopy with attowatt sensitivity over turbulent optical paths

Abstract Photon-counting dual-comb spectroscopy (DCS) opens new possibilities for deploying DCS in scenarios previously constrained by limited detection sensitivity. However, inevitable optical path fluctuations hinder its practical implementation. Here, we propose a method to ensure the long-term s...
