We report a series of measurements of the effect of an electric field on the frequency of the ultranarrow linewidth optical transition of …
High-precision methanol spectroscopy with a widely tunable SI-traceable frequency-comb-based mid-infrared QCL
R. Santagata, D. Tran, B. Argence +14
There is an increasing demand for precise molecular spectroscopy, in particular in the mid-infrared fingerprint window that hosts a considerable number of vibrational signatures, w…
A noise-immune cavity-assisted non-destructive detection for an optical lattice clock in the quantum regime
G. Vallet, E. Bookjans, U. Eismann +3
We present and implement a non-destructive detection scheme for the transition probability readout of an optical lattice clock. The scheme relies on a differential heterodyne measu…
