Coherently averaged dual-comb spectroscopy with a low-noise and high-power free-running gigahertz dual-comb laser: erratum Open
This erratum corrects a typographical error in equation (8) of our published paper [ Opt. Express 31 , 7103 ( 2023 ) 10.1364/OE.479356 ]. All the calculations used the correct equation, so all the results and conclusions remain unchanged.
