Intensity correlations in transmission and four-wave mixing signals intermediated by hot rubidium atoms
A. A. C. de Almeida, A. S. Alvarez, N. R. de Melo +3
We investigate the influence of the distribution of atom velocities in a hot rubidium sample on the correlation between field-intensity fluctuations of two independently generated…
Spatial distribution of two symmetric four-wave mixing signals induced by Gaussian beams
Mateus R. L. da Motta, Alexandre A. C. de Almeida, Sandra S. Vianna
We present a theoretical analysis of the spatial shape of two symmetric signals of degenerate four-wave mixing induced by Gaussian beams in a thin sample of two-level atoms. Our ca…
Two symmetric four-wave mixing signals generated in a medium with anomalous refractive index
A. S. Alvarez, A. A. C. de Almeida, S. S. Vianna
We report experimental and theoretical results of two symmetrical signals of degenerate four-wave mixing generated in rubidium vapor. Both nonlinear signals are induced by two almo…
