Journal ArticleDOI
High-resolution hyperfine spectroscopy of excited states using electromagnetically induced transparency
TL;DR: In this article, the authors used the phenomenon of electromagnetically induced transparency in a three-level atomic system for hyperfine spectroscopy of upper states that are not directly coupled to the ground state.
Journal ArticleDOI
Cooperative Emission of a Coherent Superflash of Light
Chang Chi Kwong,Tzyh Haur Yang,M. S. Pramod,Kanhaiya Pandey,Dominique Delande,Romain Pierrat,David Wilkowski +6 more
TL;DR: A coherent super flash is observed just after an abrupt probe extinction, with peak intensity more than three times the incident one, and it is shown that this coherent superflash is a direct signature of the cooperative forward emission of the atoms.
Journal ArticleDOI
A high flux source of cold strontium atoms
Tao Yang,Kanhaiya Pandey,M. S. Pramod,Frederic Leroux,Chang Chi Kwong,Elnur Hajiyev,Zhong Yi Chia,Bess Fang,David Wilkowski,David Wilkowski,David Wilkowski +10 more
TL;DR: In this paper, a two dimensional magneto-optical trap deflector located after a Zeeman slower was used to achieve a loading rate of 6 × 109 s−1 whereas the lifetime of the magnetically trapped atoms in the 3P2 state is 54 s.
Journal ArticleDOI
Non-Abelian adiabatic geometric transformations in a cold strontium gas.
Frederic Leroux,Kanhaiya Pandey,R. Rehbi,R. Rehbi,Frédéric Chevy,Christian Miniatura,Benoît Grémaud,Benoît Grémaud,David Wilkowski,David Wilkowski,David Wilkowski +10 more
TL;DR: In this paper, a laser-cooled gas of strontium atoms coupled to laser fields through a 4-level resonant tripod scheme was studied, where the relative phases of the tripod beams were cycled to realize non-Abelian SU(2) geometrical transformations acting on the dark states of the system.
Journal ArticleDOI
Coherent control of magneto-optic rotation
TL;DR: In this article, the rotation of the plane of polarization of a laser beam passing through room-temperature Rb vapour was studied. Butler et al. showed that the rotation occurs because the medium behaves differently for the two orthogonallypolarized components, displaying what is known as circular birefringence or linear dichroism.
