Selective reflection from a Potassium atomic layer with a thickness as small as
Armen Sargsyan, Emmanuel Klinger, Claude Leroy +3
We demonstrate that a method using the derivative of the selective reflection signal from a nanocell is a convenient and robust tool for atomic laser spectroscopy, achieving a near…
Measurement of the atom-surface van der Waals interaction by transmission spectroscopy in a wedged nano-cell
T. Peyrot, N. Šibalić, Y. R. P. Sortais +5
We demonstrate a method for measuring atom-surface interactions using transmission spectroscopy of thermal vapors confined in a wedged nano-cell. The wedged shape of the cell allow…
The Collective Lamb Shift of a Nanoscale Atomic Vapour Layer within a Sapphire Cavity
T. Peyrot, Y. R. P. Sortais, A. Browaeys +5
We measure the near-resonant transmission of light through a dense medium of potassium vapor confined in a cell with nanometer thickness in order to investigate the origin and vali…
Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen-Back regime
Daniel J. Whiting, Renju S. Mathew, James Keaveney +2
We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S, 5P, 5P and 5D terms) i…
Single-photon interference due to motion in an atomic collective excitation
Daniel J. Whiting, Nikola Sibalic, James Keaveney +2
We experimentally demonstrate the generation of heralded bi-chromatic single photons from an atomic collective spin excitation (CSE). The photon arrival times display collective qu…
Spectroscopic detection of atom-surface interactions in an atomic vapour layer with nanoscale thickness
K. A. Whittaker, J. Keaveney, I. G. Hughes +3
We measure the resonance line shape of atomic vapor layers with nanoscale thickness confined between two sapphire windows. The measurement is performed by scanning a probe laser th…
