Intensity correlations in the forward four-wave mixing driven by a single pump
A. A. C. de Almeida, M. R. L. da Motta, S. S. Vianna
We study the field intensity fluctuations of two independent four-wave mixing signals generated in a cold rubidium sample as well as the transmission signals. We employ an experime…
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…
Dynamic Stark shift in a Doppler-broadened four-wave mixing
M. P. M. de Souza, A. A. C. de Almeida, S. S. Vianna
This work presents a theoretical analysis of the Autler-Townes splitting pattern in the four-wave mixing signal generated in a three-level cascade Doppler-broadened system. We empl…
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…
Interference effect and Autler-Townes splitting in coherent blue light generated by four-wave mixing
M. P. Moreno, A. A. C. de Almeida, S. S. Vianna
An unexpected interference effect between four-wave mixing excitation routes in rubidium vapor is observed using a combination of a cw diode laser and a 1 GHz femtosecond pulse tra…
