Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble
D. Moretti, D. Felinto, J. W. R. Tabosa
We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed i…
Dynamics of saturated Bragg diffraction in a stored light grating in cold atoms
D. Moretti, N. Gonzalez, D. Felinto +1
We report on a detailed investigation of the dynamics and the saturation of a light grating stored in a sample of cold cesium atoms. We employ Bragg diffraction to retrieve the sto…
Spectroscopic observation of the rotational Doppler effect
S. Barreiro, J. W. R. Tabosa, H. Failache +1
We report on the first spectroscopic observation of the rotational Doppler shift associated with light beams carrying orbital angular momentum. The effect is evidenced as the broad…
