Line shapes of atomic transitions in excited dense gas

Vladimir A. Sautenkov

We discuss recently published results of experimental studies of dipole-dipole broadened line shapes in excited atomic vapors. The Lorentz local-field shift and self-broadened width were measured in optically excited potassium and rubidium vapors. Strong reduction of the shift and width was observed. This effect allowed resolve electromagnetically induced dressed states inside the self-broadened spectral profile. The experimental results were interpreted using well-known models of the dipole-dipole interactions.We discuss recently published results of experimental studies of dipole-dipole broadened line shapes in excited atomic vapors.

Collision and static widths of self-broadened line shapes in optically saturated high-density atomic vapor

Vladimir A. Sautenkov, Sergey Saakyan, A.V. Bobrov +2 more

We study the frequency derivatives of selective reflection from high-density rubidium vapor using a hole-burning technique. Saturation dips are observed inside the self-broadened line shapes. The line self-broadening is a combination of static width and collision width. By analyzing saturation dips, we can separate power broadening and collision width. Our experimental results support the theory of inhomogeneous dipole-dipole induced broadening of transitions in a dense atomic gas, published by J. A. Leegwater and S. Mukamel [Phys. Rev. A 49 (1994) 146].We study the frequency derivatives of selective reflection from high-density rubidium vapor using a hole-burning technique.
