We present experimental results on the transfer of the orbital angular momentum of light to a
system of cold cesium atoms. A nondegenerate four-wave mixing process was used as an …

Creation, erasing and ultrafast control of population density gratings using few-cycle optical
pulses coherently interacting with resonant medium is discussed. In contrast to the …

We have experimentally investigated laser diffraction on electromagnetically induced
gratings in a degenerate open two-level system. The experiment employs the standard …

We experimentally demonstrate the high-efficiency reflection of a probe field in Λ-type three-
level atoms of cesium vapor driven by two counterpropagating coupling fields. More than …

The phase compensation mechanism induced by anomalous dispersion in the reflection
process of four-wave mixing (or reflection from a grating) in a three-level system is …

We report the observation of transient Bragg diffraction by an optical-pum**-transferred
ground-state population grating in cold cesium atoms confined in a magneto-optical trap …

We report on the storage of light via the phenomenon of coherent population oscillation
(CPO) in an atomic cesium vapor at room temperature. In the experiment the optical …

We experimentally demonstrate dressed multi-wave mixing (MWM) and the reflection of the
probe beam due to electromagnetically induced absorption (EIA) grating can coexist in a five …

We have monitored the third and the fifth order nonlinear susceptibilities of cold cesium
atoms confined in a magneto-optical trap through the observation of Bragg diffraction into a …
