Electromagnetically induced transparency in multi-level cascade scheme of cold rubidium atoms
We report an experimental investigation of electromagnetically induced transparency in a multilevel cascade system of cold atoms. The absorption spectral profiles of the probe light in the multi-level cascade system were observed in cold Rb atoms confined in a magneto-optical trap, and the dependence of the spectral profile on the intensity of the coupling laser was investigated. The experiment...
متن کاملMagneto Optical Trapping of Rb 87
Magneto optical traps brilliantly combine semi-classical optics with modern physics. By carefully controlling the polarization and frequency of laser beams, it is possible to trap and cool atoms down to the millikelvin range at a relatively low cost. This has opened previously inaccessible physical domains to enterprising physicists all around the world, and is responsible for some of the most ...
متن کاملBright narrowband biphoton generation from a hot rubidium atomic vapor cell
We demonstrate the generation of high-quality narrowband biphotons from a Doppler-broadened hot rubidium atomic vapor cell. Choosing a double-K atomic energy level scheme for optimizing both spontaneous four-wave mixing nonlinear parametric interaction and electromagnetically induced transparency (EIT), we achieve a biphoton spectral brightness as high as 14 000 s MHz . Meanwhile, we apply a sp...
متن کاملEvidence of lasing without inversion in a hot rubidium vapor under electromagnetically-induced-transparency conditions
We report a likely observation of cw lasing without inversion in a gas of hot rubidium atoms in an optical cavity under conditions of electromagnetically induced transparency EIT . The medium is pumped coherently and resonantly by a single “coupling” beam which also produces EIT in the lasing transition. The steady-state intensity exhibits thresholds as a function of the atomic density and the ...
متن کاملMatched slow pulses using double electromagnetically induced transparency.
We implement double electromagnetically induced transparency (DEIT) in rubidium vapor using a tripod-shaped energy-level scheme consisting of hyperfine magnetic sublevels of the 5S1/2-->5P1/2 transition. We show experimentally that through the use of DEIT one can control the contrast of transparency windows as well as group velocities of the two signal fields. In particular, the group velocitie...
