Bicolor Fiber-Cavity-Enhanced Dual-Comb Spectro-Microscopy
Cavity-enhanced dual-comb spectroscopy combines high sensitivity, resolution and broad bandwidth, making it a powerful tool for gas-phase spectroscopy [1]. Existing implementations require complex dispersion management of the cavity mirrors and tight feedback locking for comb-cavity coupling. In this work, we present a novel approach to cavity-enhanced condensed-phase spectroscopy that enables spectrally and spatially resolved measurements without the need for dispersion management and feedback stabilisation.
