Self-action of laser radiation under the conditions of electromagnetically induced transparency
N. A. Zharova, A. G. Litvak, V. A. Mironov Institute of Applied Physics, Russian Academy of Sciences, Nizhnii Novgorod
Abstract:
The laser-radiation self-action dynamics in the electromagnetically induced transparency band were studied analytically and numerically for an atomic gas with the $\Lambda$-type energy-level scheme. The self-consistent system of equations describing the spatiotemporal evolution of a finite-amplitude wave packet in the field of a uniform pump wave was derived. The self-action in the presence of competing diffraction, nonlinear dispersion, and radiation absorption in the system was qualitatively analyzed; in particular, the conditions for self-focusing of a probe beam were determined. The results were confirmed by the numerical simulation of wave-packet spatiotemporal evolution.
