Image Transfer through Two Sequential Four-Wave Mixing in a Hot Atomic Vapor
Image Transfer Two Sequential Four-Wave Hot Atomic Vapor Optics
2012/5/31
Efficient wavelength conversion of images has many potential applications in optical communication, sensing, imaging, and quantum information fields. In this work, we report on here the first demonstr...
Polarization squeezing of light by single passage through an atomic vapor
Polarization squeezing single passage atomic vapor
2011/8/17
Abstract: We have studied relative-intensity fluctuations for a variable set of orthogonal elliptic polarization components of a linearly polarized laser beam traversing a resonant $^{87}$Rb vapor cel...
Enhanced reflection via phase compensation from anomalous dispersion in atomic vapor
Enhanced reflection phase compensation anomalous dispersion atomic vapor
2014/5/28
The phase compensation mechanism induced by anomalous dispersion in the reflection process of four-wave mixing (or reflection from a grating) in a three-level system is investigated, where the four wa...
Ultra-bright biphoton emission from an atomic vapor based on Doppler-free four-wave-mixing and collective emission
atomic vapor Doppler-free four-wave-mixing biphoton emission
2010/4/12
We propose a novel `butterfly' level scheme to generate highly correlated photon pairs from atomic vapors. With multi-photon Doppler-free pumping, background Rayleigh scattering is dipole-forbidden an...
