Autler-Townes spectroscopy of the $5S_{1/2}-5P_{3/2}-44D$ cascade of cold ${}^{85}$Rb atoms

B. K. Teo, D. Feldbaum, T. Cubel +3

We study nonlinear optical effects in the laser excitation of Rydberg states. $5S_{1/2}$ and $5P_{3/2}$ levels of ${}^{85}$Rb are strongly coupled by a strong laser field and probed…
