Transient optical response of cold Rydberg atoms with electromagnetically induced transparency

We investigate the linear and nonlinear optical response to an optical pumping of a four-level atomic system with electromagnetically induced transparency (EIT) in a cold Rydberg atomic gas. It is found that the transient behavior (especially, the third- and fifth-order susceptibilities) of the probe field, and the steady-state EIT spectrum of the gas, depend crucially on the Rydberg atoms' interaction. Furthermore, we find that the response speed of the Rydberg interaction with EIT can be as much as six times faster than the EIT without the Rydberg interaction, and that the nonlinear response time of the fifth-order optical susceptibility is longer than that of the third-order susceptibility. It is established that the Rydberg blockade effect plays a significant role in increasing the response speed of the Rydberg with EIT.

Laser frequency stabilization to excited Rydberg transitions using electromagnetically induced transparency

Marcel.li Grimau Puigibert

[ANGLÈS] Rydberg atoms with principal quantum number n>>1 have extraordinary atomic properties including tunable long range dipole-dipole interactions that lead to the so called Rydberg blockade. Atoms excited to these particular levels have been shown to be excellent candidates to implement several quantum information tasks, from two-qubit gates to single photon sources. In this work, we demonstrate Electromagnetic Induced Transparency (EIT) using Rydberg levels in a hot gas of rubidium atoms. We then use the EIT window as a reference to stabilize the frequency of the coupling laser.
