Correlated photon pairs generated from a warm atomic ensemble
R. T. Willis, F. E. Becerra, L. A. Orozco +1
We present measurements of the cross-correlation function of photon pairs at 780 nm and 1367 nm, generated in a hot rubidium vapor cell. The temporal character of the biphoton is d…
Non-degenerate four-wave mixing in rubidium vapor: transient regime
F. E. Becerra, R. T. Willis, S. L. Rolston +2
We investigate the transient response of the generated light from Four-Wave Mixing (FWM) in the diamond configuration using a step-down field excitation. The transients show fast d…
Two-Photon Dichroic Atomic Vapor Laser Lock Using Electromagnetically Induced Transparency and Absorption
F. E. Becerra, R. T. Willis, S. L. Rolston +1
We demonstrate a technique to lock the frequency of a laser to a transition between two excited states in Rb vapor in the presence of a weak magnetic field. We use a ladder configu…
