Massively parallel detection of trace molecules in a mixture using an ultra-broadband mid-IR subharmonic dual comb

We use a pair of highly-coherent GaAs subharmonic OPOs with instantaneous span 3.1-5.5 µm to demonstrate fast acquisition of 350, 000 mode-resolved spectral data points and perform parallel detection in a mixture of 22 molecular species.
