Temporal dynamics of Levy flights of photons in a three-dimensional geometry for hot vapor
Ricardo V. M. de Almeida Filho, Joao C. de Aquino Carvalho, Thierry Passerat de Silans +2
Multiple scattering of light by resonant vapor is characterized by Lévy-type superdiffusion with a step size distribution , with . The Lévy parame…
Comparison between 403 nm and 497 nm repumping schemes for strontium magneto-optical traps
P H Moriya, M O Araújo, F Todão +5
The theoretical description of the external degrees of freedom of atoms trapped inside a magneto-optical trap (MOT) often relies on the decoupling of the evolution of the internal…
Subradiance and radiation trapping in cold atoms
Patrizia Weiss, Michelle O. Araújo, Robin Kaiser +1
We experimentally and numerically study the temporal dynamics of light scattered by large clouds of cold atoms after the exciting laser is switched off in the low intensity (linear…
Stabilization of a laser on a large-detuned atomic-reference frequency by resonant interferometry
Priscila M. T. Barboza, Guilherme G. Nascimento, Michelle O. Araújo +5
We report a simple technique for stabilization of a laser frequency at the wings of an atomic resonance. The reference signal used for stabilization issues from interference effect…
Measurement of the Kerr nonlinear refractive index of Cs vapor
Michelle O. Araújo, Hugo L. D. de S. Cavalcante, Marcos Oriá +4
Atomic vapors are systems well suited for nonlinear optics studies but very few direct measurements of their nonlinear refractive index have been reported. Here we use the z-scan t…
