WebMar 1, 2024 · Using the two-color two-photon scheme, caesium (Cs) atoms were excited to (or around) the 11 2 D 5/2 level, generating terahertz (THz) and infrared (IR) radiations. then, a series of collimated ultraviolet (UV) lights were obtained through the four-wave mixing process. There was a competition among the collimated UV lights. WebThe structure of such polarization was revealed by nearly degenerate four-wave-mixing processes. We report an experimental demonstration that shows that the spatial structure carried by engineered coherent superpositions of light beams with orbital angular momentum can be mapped into the nonlinear polarization induced in a cloud of cold …
WebWe observed low-intensity cw degenerate four-wave mixing at the D1 resonance in a 10-μm-thick cesium-vapor cell. Normal population depletion caused by optical pumping is alleviated by frequent atom–wall collisions. The reflectivity at the D1 resonance is approximately equal in magnitude to that observed at the D2 cycling transition under … WebOct 17, 2024 · Using a nondegenerate four-wave mixing process based on a double-Λ scheme in hot cesium vapor, we generate quantum correlated twin beams with a …
