Relative Intensity Squeezing by Four-Wave Mixing in Rubidium

squeezed light through four-wave mixing in a rubidium vapour. Relative intensity squeez-ing enhances measurement precision by using quantum-correlated “twin beams” to elimi-nate photon shot-noise. The “double- ” four-wave mixing process produces twin beams

Generation of Airy beams by four-wave mixing in Rubidium

We report on an experimental generation of Airy beams by four-wave mixing (FWM) in atomic vapor cells. This is achieved by using a non-degenerate FWM process, which occurs with two Gaussian pump beams and one Airy signal beam in hot Rubidium vapor. After satisfying the phase matching condition, a FWM field with the profile of an Airy beam can be generated.

All-Optical Switching in Rubidium Vapor Science

Apr 29, 2005 We report on an all-optical switch that operates at low light levels. It consists of laser beams counterpropagating through a warm rubidium vapor that induce an off-axis optical pattern. A switching laser beam causes this pattern to rotate even when the power in the switching beam is much lower than the power in the pattern. The observed switching energy density is very low, suggesting

In this paper, we briefly review the recent experimental progresses in quantum optics based on four-wave mixing (FWM) processes in hot rubidium vapor, particularly our two recent experiments in quantum information. We have experimentally produced strong quantum correlations between three bright beams generated by two cascaded FWM processes. The intensity difference squeezing with the cascaded

Oct 26, 2018 Rubidium atoms can be coherently excited to Rydberg states in vapor cells of such a size, without being limited by atom-wall interactions . Therefore, it has been predicted that a four-wave mixing experiment in a microscopic cell will result in a suppression of multiple excitations and hence to an emission of single photons ( 29 ).

High-efficiency frequency conversion of OAM is possible via four-wave mixing in rubidium vapour. Conservation of the OAM in the two pump beams determines the total OAM shared by the generated light fields at 420nm and 5.2μm—but not its distribution between them. Here we experimentally investigate the spiral bandwidth of the generated

Terahertz emitting and four wave mixing details in 6P3/2

Sep 24, 2020 1. Introduction. The properties of FWM lights in alkali metal vapors have attracted a lot of research interests. For example, FWM happens in rubidium vapor when using 780nm (5S 1/2 →5P 3/2) and 776 nm (5P 3/2 →5D 5/2) pumping, 5.23μm (5D 5/2 →6P 3/2) and 420 nm (6P 3/2 →5S 1/2) directional lights occur.Similar phenomena are sometime referred to as mirror-less lasers.
