Doppler-compensated three-photon electromagnetically induced transparency
Doppler-compensated three-photon electromagnetically transparency Atomic Physics
2012/5/31
We demonstrate Doppler-compensated bright and dark states in a resonant four-level atomic system. The spectral features are the result of electromagnetically induced transparency (EIT) and absorption ...
Interferometric thermometry of a single sub-Doppler cooled atom
Interferometric thermometry single sub-Doppler cooled atom
2012/2/28
Efficient self-interference of single-photons emitted by a sideband-cooled Barium ion is demonstrated. First, the technical tools for performing efficient coupling to the quadrupolar transition of a s...
Doppler cooling to the Quantum limit
Doppler Quantum limit Atomic Physics single scattering events
2011/8/4
Abstract: Doppler cooling on a narrow transition is limited by the noise of single scattering events. It shows novel features, which are in sharp contrast with cooling on a broad transition, such as a...
Sub-Doppler laser cooling of potassium atoms
Sub-Doppler laser potassium atoms Quantum Gases
2011/8/4
Abstract: We investigate sub-Doppler laser cooling of bosonic potassium isotopes, whose small hyperfine splitting has so far prevented cooling below the Doppler temperature. We find instead that the c...
Doppler-free two-photon resonances for atom detection and sum frequency stabilization
Doppler-free two-photon atom
2011/8/29
We investigate the excitation of the 5D5/2 level in Rb atoms using counterpropagating laser beams, which are nearly resonant to the one-photon 5S1/2 !5P3/2 and 5P3/2 ! 5D5/2 transitions, ensuring that...
Ultra-bright biphoton emission from an atomic vapor based on Doppler-free four-wave-mixing and collective emission
atomic vapor Doppler-free four-wave-mixing biphoton emission
2010/4/12
We propose a novel `butterfly' level scheme to generate highly correlated photon pairs from atomic vapors. With multi-photon Doppler-free pumping, background Rayleigh scattering is dipole-forbidden an...
