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…
Narrow band amplification of light carrying orbital angular momentum
G. C. Borba, S. Barreiro, L. Pruvost +2
We report on the amplification of an optical vortex beam carrying orbital angular momentum via induced narrow Raman gain in an ensemble of cold cesium atoms. A 20\% single-pass Ram…
Storage of orbital angular momenta of light via coherent population oscillation
A. J. F. de Almeida, S. Barreiro, W. S. Martins +3
We report on the storage of Orbital Angular Momentum (OAM) of light via the phenomenon of Coherent Population Oscillation (CPO) in cold cesium atoms. The experiment is performed us…
Experimental characterization of the Gaussian state of squeezed light obtained via single-passage through an atomic vapor
P. Valente, A. Auyuanet, S. Barreiro +2
We show that the description of light in terms of Stokes operators in combination with the assumption of Gaussian statistics results in a dramatic simplification of the experimenta…
Off-axis retrieval of orbital angular momentum of light stored in cold atoms
R. A. de Oliveira, L. Pruvost, P. S. Barbosa +5
We report on the storage of orbital angu- lar momentum (OAM) of light of a Laguerre-Gaussian mode in an ensemble of cold cesium atoms and its re- trieval along an axis different fr…
Vectorial atomic magnetometer based on coherent transients of laser absorption in Rb vapor
L. Lenci, A. Auyuanet, S. Barreiro +3
We have designed and tested an atomic vectorial magnetometer based on the analysis of the coherent oscillatory transients in the transmission of resonant laser light through a Rb v…
