Nonlinear system synchronization to sum signals of multiple chaotic systems
Robson Vieira, Weliton S. Martins, Sergio Barreiro +3
Coupling of chaotic oscillators has evidenced conditions where synchronization is possible, therefore a nonlinear system can be driven to a particular state through input from a si…
Backward-emitted sub-Doppler fluorescence from an optically thick atomic vapor
João Carlos de Aquino Carvalho, Athanasios Laliotis, Martine Chevrollier +2
Literature mentions only incidentally a sub-Doppler contribution in the excitation spectrum of the backward fluorescence of a dense vapor. This contribution is here investigated on…
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…
On the temporal wavefunction in quantum physics - a short note
Martine Chevrollier, Marcos Oriá
Experiments involving single or few elementary particles are completely described by Quantum Mechanics. Notwithstanding the success of that quantitative description, various aspect…
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…
Laser-induced atomic adsorption: a mechanism for nanofilm formation
Weliton S. Martins, Thierry Passerat de Silans, Marcos Oriá +1
We demonstrate and interpret a technique of laser-induced formation of thin metallic films using alkali atoms on the window of a dense-vapour cell. We show that this intriguing pho…
