Adaptive dual-comb spectroscopy in the green region

Abstract

Dual-comb spectroscopy is extended to the visible spectral range with two short-pulse frequency-doubled free-running ytterbium-doped fiber lasers. When the spectrum is shifted to other domains by nonlinear frequency conversion, tracking the relative fluctuations of the femtosecond oscillators at their fundamental wavelength automatically produces the correction signal needed for the recording of distortion-free spectra. The dense rovibronic spectrum of iodine around $19,240{\mathrm{cm}}^{-1}$ is recorded within 12 ms at Doppler-limited resolution.
