Intensity Correlated Spiking Emission Due to Cooperative Effects in Alkali Vapors
Alexander M. Akulshin, Nafia Rahaman, F. Pedreros Bustos +3
Spiking behavior and a high degree of intensity correlation of frequency up- and down-converted directional radiation from population-inverted alkali vapors excited with a continuo…
Parametric wave mixing enhanced by velocity insensitive two-photon excitation in Rb vapour
Alexander M. Akulshin, Dmitry Budker, Russell J. McLean
We demonstrate how the orientation of the Rb cell can significantly affect the intensity and spectral characteristics of both the frequency up- and down-converted fields generated…
Arithmetic with optical topological charged in step-wise excited Rb vapour
Alexander M. Akulshin, Irina Novikova, Eugeniy E. Mikhailov +2
We report on experimentally observed addition, subtraction and cancellation of orbital angular momentum (OAM) in the process of parametric four-wave mixing that results in frequenc…
Distinguishing nonlinear processes in atomic media via orbital angular momentum transfer
Alexander M. Akulshin, Russell J. McLean, Eugeniy E. Mikhailov +1
We suggest a technique based on the transfer of topological charge from applied laser radiation to directional and coherent optical fields generated in ladder-type excited atomic m…
Collimated blue light generated by four-wave mixing in Rb vapour
Alexander M. Akulshin, Russell J. McLean, Andrei I. Sidorov +1
We investigate frequency up-conversion of low power cw resonant radiation in Rb vapour as a function of various experimental parameters. We present evidence that the process of fou…
Delay of Squeezing and Entanglement using Electromagnetically Induced Transparency in a Vapour Cell
G. Hétet, B. C. Buchler, O. Glöckl +4
We demonstrate experimentally the delay of squeezed light and entanglement using Electromagnetically Induced Transparency (EIT) in a rubidium vapour cell. We perform quadrature amp…
