Highly Sensitive Dual Comb Spectroscopy Using Background Suppressed Spectral Peaking at λ = 1.65 μm
Highly sensitive dual-comb spectroscopy was demonstrated using background-suppressed spectral peaking. A high SNR of 38 dB and a large dynamic range of 50 dB were achieved for comb mode resolved CH 4 absorption measurement.
