Spectroscopic detection of atom-surface interactions in an atomic-vapor layer with nanoscale thickness.

Whittaker, K. A. and Keaveney, J. and Hughes, I. G. and Sargsyan, A. and Sarkisyan, D. and Adams, C. S. (2015) 'Spectroscopic detection of atom-surface interactions in an atomic-vapor layer with nanoscale thickness.', Physical review A., 92 (5). 052706.


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 through resonance and collecting the scattered light. The line shape is dominated by the effects of Dicke narrowing, self-broadening, and atom-surface interactions. By fitting the measured line shape to a simple model we discuss the possibility to extract information about the atom-surface interaction.
