The current paper reports first and definite experimental evidence for g-, X-, or b radiation causing UV dominant optical radiation from (1) radiochemicals such as 131I; (2) XRF sources such as Rb XRF...
Ultra-bright biphoton emission from an atomic vapor based on Doppler-free four-wave-mixing and collective 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...
