Abstract

We prepare a parametric self-oscillation regime in hot rubidium vapor and observe single-photon level induced ultraslow matched pulses by four-wave mixing. The delay times are dependent on the few-photon input states.

Ultraslow Propagation of Matched Pulses by Four-Wave Mixing in an Atomic Vapor

Vincent Boyer, Colin F. McCormick, E. Arimondo +1 more

We have observed the ultraslow propagation of matched pulses in nondegenerate four-wave mixing in a hot atomic vapor. Probe pulses as short as 70 ns can be delayed by a tunable time of up to 40 ns with little broadening or distortion. During the propagation, a probe pulse is amplified and generates a conjugate pulse which is faster and separates from the probe pulse before getting locked to it at a fixed delay. The precise timing of this process allows us to determine the key coefficients of the susceptibility tensor. The fact that the same configuration has been shown to generate quantum correlations makes this system very promising in the context of quantum information processing.

Ultraslow matched-pulse propagation in sodium vapor

Junji Okuma, Nobuhito Hayashi, Akihiko Fujisawa +1 more

We have observed ultraslow propagation of matched pulses in a parametric amplifying hot sodium vapor. A fractional delay of more than 1 and a gain of 28 have been simultaneously achieved for a probe pulse of width 100 ns, accompanying a conjugate Stokes pulse with similar gain and delay under a strong coupling beam. The results are compared with the preceding work by Boyer et al. [Phys. Rev. Lett. 99, 143601 (2007)].
