Influence of Many-Body Dipole-Dipole Interactions on Excitation Transfer in a Dense Gas
A. A. Bobrov, S. A. Saakyan, B. B. Zelener +1
We study non-radiative dipole-dipole induced excitation transfer in dense Rb vapour. We show that density dependence of characteristic time of the excitation diffusion changes from…

Collision and static widths of self-broadened line shapes in optically saturated high-density atomic vapor
Vladimir Sautenkov, Sergey Saakyan, Andrei Bobrov +2
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 l…

Modulation transfer spectroscopy of Li D1 line
Leonid Khalutornykh, Sergey Saakyan, Alexander Nazarov +1
We present the first implementation of modulation transfer spectroscopy (MTS) on the D line of Li, carried out in a compact heat-pipe vapor cell with cold windows. By varyin…
