Optical cooling of atoms in microtraps by time-delayed reflection
Peter Horak, André Xuereb, Tim Freegarde
We present a theoretical analysis of a novel scheme for optical cooling of particles that does not in principle require a closed optical transition. A tightly confined laser beam i…
Magneto-optical trapping and background-free imaging for atoms near nanostructured surfaces
Hamid Ohadi, Matthew Himsworth, André Xuereb +1
We demonstrate a combined magneto-optical trap and imaging system that is suitable for the investigation of cold atoms near surfaces. In particular, we are able to trap atoms close…
Rubidium Pump-Probe Spectroscopy: Comparison between ab-initio Theory and Experiment
M. Himsworth, T. Freegarde
We present a simple, analytic model for pump-probe spectroscopy in dilute atomic gases. Our model treats multilevel atoms, takes several broadening mechanisms into account and, wit…
Hänsch--Couillaud locking of Mach--Zehnder interferometer for carrier removal from a phase-modulated optical spectrum
J. E. Bateman, R. L. D. Murray, M. Himsworth +3
We describe and analyse the operation and stabilization of a Mach--Zehnder interferometer, which separates the carrier and the first-order sidebands of a phase-modulated laser fiel…
Scattering theory of multilevel atoms interacting with arbitrary radiation fields
André Xuereb, Peter Domokos, Peter Horak +1
We present a generic transfer matrix approach for the description of the interaction of atoms possessing multiple ground state and excited state sublevels with light fields. This m…
Stimulated Raman transitions via multiple atomic levels
James Bateman, André Xuereb, Tim Freegarde
We consider the stimulated Raman transition between two long-lived states via multiple intermediate states, such as between hyperfine ground states in the alkali-metal atoms. We pr…
