Fault-tolerant hyper-Ramsey spectroscopy of ultra-narrow clock transitions with dynamical decoupling
T. Zanon-Willette, B. Ilikj, D. Wilkowski +3
A probe laser field that interrogates an atomic transition also shifts it. Although Hyper-Ramsey (HR) spectroscopy was developed to mitigate these light-induced frequency shifts, t…

Wavelength modulation laser spectroscopy of NO at 17 m
Y. Wang, J. Rodewald, O. Lopez +4
Using a mid-infrared quantum cascade laser and wavelength modulation absorption spectroscopy, we measure the frequencies of ro-vibrational transitions of NO in the 17 m reg…
