Noiseless optical amplifier operating on hundreds of spatial modes.
TL;DR: A noiseless optical amplifier is implemented using a phase-sensitive four-wave mixing process in rubidium vapor and it is observed that it supports hundreds of spatial modes, making it possible to amplify complex two-dimensional spatial patterns with less than a 10% degradation of the input signal-to-noise ratio.

Quantum correlated light beams from non-degenerate four-wave mixing in an atomic vapor: the D1 and D2 lines of 85Rb and 87Rb.
TL;DR: The observation of quantum correlations on light produced using all four of these systems, regardless of their substructure, suggests that it should be possible to use other systems with similar level structures in order to produce narrow frequency, non-classical beams at a particular wavelength.

Light storage in a room temperature atomic vapor based on coherent population oscillations
TL;DR: In this article, the experimental observation of coherent population oscillation (CPO)-based light storage in an atomic vapor cell at room temperature is reported. But it does not involve any atomic coherences and has the advantage of being robust to dephasing effects such as small magnetic field inhomogeneities.
