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…
Redistribution of light frequency by multiple scattering in a resonant atomic vapor
J. C. de A. Carvalho, H. L. D. de Souza Cavalcante, M. Oriá +2
The propagation of light in a resonant atomic vapor can \textit{a priori} be thought of as a multiple scattering process, in which each scattering event redistributes both the dire…
Two-beam nonlinear Kerr effect to stabilize laser frequency with sub-Doppler resolution
Weliton Soares Martins, Hugo L. D. de S. Cavalcante, Thierry Passerat de Silans +2
Avoiding laser frequency drifts is a key issue in many atomic physics experiments. Several techniques have been developed to lock the laser frequency using sub-Doppler dispersive a…
Quantum scaling laws in the onset of dynamical delocalization
Julien Chabé, Hans Lignier, Hugo L. D. De Souza Cavalcante +3
We study the destruction of dynamical localization, experimentally observed in an atomic realization of the kicked rotor, by a deterministic Hamiltonian perturbation, with a tempor…
Exponential Recovery of Low Frequency Fluctuations in a Diode Laser with Optical Feedback
Jhon Fredy Martinez Avila, J. R. Rios Leite, Hugo L. D. de S. Cavalcante
We show that the recovery after each power drop on the chaotic Low Frequency Fluctuations in a semiconductor laser with optical feedback follows an exponential envelope. The time c…
Phase-space reconstruction of an atomic chaotic system
Hugo L. D. De Souza Cavalcante, Carlos Renato De Carvalho, Jean Claude Garreau
We consider the dynamics of a single atom submitted to periodic pulses of a far-detuned standing wave generated by a high-finesse optical cavity, which is an atomic version of the…
