“…When atoms are excited to Rydberg states, several ionization channels are possible. In a dense ultra cold cloud they can evolve into ions via dipole-dipole interaction [29,30] or photo ionization due to the trapping laser [31] or black body radiation [32]. In the case of photo ionization the amount of ions is proportional to the excitation probability to the Rydberg state and is a direct measure of the excitation rate.…”

We report on the realization of high resolution electron microscopy of Rydbergexcited ultracold atomic samples. The implementation of an ultraviolet laser system allows us to excite the atom, with a single-photon transition, to Rydberg states. By using the electron microscopy technique during the Rydberg excitation of the atoms, we observe a giant enhancement in the production of ions. This is due to l-changing collisions, which broaden the Rydberg level and therefore increase the excitation rate of Rydberg atoms. Our results pave the way for the high resolution spatial detection of Rydberg atoms in an atomic sample. − 500 V cm 1 ) or electric field gradients ( − 200 V cm 2 ) in the center of the chamber, which are of 2 New J.

“…In particular, only a specific combination of the two modes can be perfectly absorbed and recovered [24,36,37], whereas for an arbitrary two-frequency-mode input, part of the light will propagate transparently and part will be absorbed [24]. Nonetheless, it has been shown that the four-wave mixing processes arising in double-media, which make difficult the implementation of a suitable quantum memory, have interesting applications in frequency conversion of classical probe beams [36,38], single-photon frequency conversion preserving the quantum coherence [35], and in the possibility to combine or redistribute one or two previously stored frequency modes [23,27,37], even with different relative intensities [24]. An interesting situation is found when one of the two systems of the double-configuration is far detuned from the one photon resonance.…”

We propose a quantum memory for a single-photon wave packet in a superposition of two different colors, i.e., two different frequency components, using the electromagnetically induced transparency technique in a double-system. We examine a specific configuration in which the two frequency components are able to exchange energy through a four-wave mixing process as they propagate, so the state of the incident photon is recovered periodically at certain positions in the medium. We investigate the propagation dynamics as a function of the relative phase between the coupling beams and the input single-photon frequency components. Moreover, by considering time-dependent coupling beams, we numerically simulate the storage and retrieval of a two-frequency-component single-photon qubit.
