Dual-comb laser enables broadband detection of optical anisotropies

Résumé

The measurement of optical anisotropies is widely employed in many application fields, such as material and biomedical sciences. Such spectroscopic method monitors the polarization state alterations after the interaction between matter and different states of polarized light. Here, we use a newly developed single-cavity dual-comb laser to demonstrate proof-of-principle polarization-resolved measurements. We detect the signals resulting from the heterodyne mixing of the two combs. The interferograms encode the information about the polarimetric properties of samples at kHz rate. Our results complement earlier work with similar single-cavity dual-comb lasers demonstrating pump-probe sampling, and pave the way for a new platform for multimodal sensing.
