Doppler-Free Two-Photon Cavity Ring-Down Spectroscopy of a Nitrous Oxide (NO) Vibrational Overtone Transition
Gang Zhao, D. Michelle Bailey, Adam J. Fleisher +2
We report Doppler-free two-photon absorption of NO at = 4.53 m, measured by cavity ring-down spectroscopy. High power was achieved by optical self-locking of a quantum c…
