Abstract

By using a sodium atomic vapor we have observed a honeycomb-type multiple-diffraction pattern that was due to a grating induced optically by three noncollinear bichromatic excitation beams. In particular, when the two incident frequencies satisfy the two-photon resonance condition and the atomic density is high, the diffraction is enhanced by electromagnetically induced transparency, and strong Stokes and anti-Stokes components are generated in well-defined directions.

Four-wave parametric oscillation in sodium vapor by electromagnetically induced diffraction

Ken-ichi Harada, Minoru Ogata, Masaharu Mitsunaga

We have observed a novel type of parametric oscillation in sodium atomic vapor where four off-axis signal waves simultaneously build up under resonant and counterpropagating pump beams with elliptical beam profiles. The four waves, two of them Stokes shifted and the other two anti-Stokes shifted, have similar output powers of up to 10 mW with a conversion efficiency of 30% and are parametrically coupled by electromagnetically induced diffraction.

Observation of diffraction pattern in two-dimensional optically induced atomic lattice

Jinpeng Yuan, Chaohua Wu, Lirong Wang +2 more

The diffraction pattern of a two-dimensional optically induced atomic lattice is reported experimentally in a three-level atomic system. Such a two-dimensional optical lattice is established by two orthogonal standing-wave fields induced by the interference of two pairs of coupling laser beams. When the probe beam is launched into it, a spatially modulated discrete diffraction pattern can be obtained at the output plane of the vapor cell under the electromagnetically induced transparency condition. We investigate the diffraction pattern under different experimental parameters and find that it can be effectively controlled by tuning the coupling laser power and two-photon detuning. Our work may potentially pave the way for studying the control of light and other intriguing physical phenomena based on such a periodically modulated atomic lattice.

Observation of an electromagnetically induced grating in cold sodium atoms

Masaharu Mitsunaga, Nobuyuki Imoto

We have observed diffraction signals by a grating originating from electromagnetically induced transparency (EIT) in a three-level \ensuremath{\Lambda} system of cold sodium atoms. Theoretical and experimental analyses of this phenomenon, called the electromagnetically induced grating (EIG), have revealed that EIG spectra exhibit background-free, Lorentzian signal profiles regardless of the pump frequencies, making a clear contrast to the case of ordinary EIT spectra.

Parametric amplification in electromagnetically induced transparency

In an ordinary electromagnetically-induced-transparency setup in sodium vapor, we have observed a probe gain up to 15, attributable to the parametric amplification, accompanying the Stokes (or anti-Stokes) wave with similar output intensity.
