Quantum-noise-limited optical frequency comb spectroscopy

Aleksandra Foltynowicz, Ticijana Ban, Piotr Maslowski +2

We achieve a quantum-noise-limited absorption sensitivity of 1.7/times10${}^{-12}$ cm${}^{-1}$ per spectral element at 400 s of acquisition time with cavity-enhanced frequency comb spe…
