Laser Cooling and Trapping of Li

Japanese Journal of Applied Physics, 1991
Neutral 7Li and 6Li atoms are laser cooled and trapped using the 22P3/2(F=3)↔22S1/2(F=2) and 22P3/2(F=5/2)↔22S1/2(F=3/2) transitions, respectively. The Zeeman tuning is employed in the deceleration stage. Using a magneto-optical trap with a tetrahedral laser-beam configuration the atomic density of 3×109 atoms/cm3 is obtained for 7Li and a half of

Trapped Ions, Laser Cooling, and Better Clocks

Science, 1984
Ions that are stored in electromagnetic "traps" provide the basis for extremely high resolution spectroscopy. By using lasers, the kinetic energy of the ions can be cooled to millikelvin temperatures, thereby suppressing Doppler frequency shifts.

Laser cooling and trapping of francium

2005
An apparatus to produce francium atoms and to trap them in a magneto-optical trap (MOT) has been set up at the Legnaro INFN National Laboratories (Italy). A detailed description of the main parts of the apparatus is given together with step-by-step measurements characterizing the production, transport, neutralization, and trapping of the radioactive ...

Laser-cooling and electromagnetic trapping of neutral atoms

AIP Conference Proceedings, 1985
Until recently it has been impossible to confine and trap neutral atoms using electromagnetic fields. While many proposals for such traps exist, the small potential energy depth of the traps and the high kinetic energy of available atoms prevented trapping. We review various schemes for atom trapping, the advances in laser cooling of atomic beams which

Laser cooling and trapping of Ne metastable atoms

Physical Review A, 1989
A neon atomic beam in the metastable state 1${s}_{5}$ has been decelerated and trapped by the spontaneous light force of a resonant laser in a quadrupole magnetic field. Trapping has been achieved on all isotopes $^{20}\mathrm{Ne}$, $^{21}\mathrm{Ne}$, and $^{22}\mathrm{Ne}$ using a sample with natural abundance. For $^{20}\mathrm{Ne}$, approximately 4\

Laser Cooling and Magnetic Trapping at Several Tesla

Physical Review Letters, 2005
Laser cooling and magnetic trapping of (85)Rb atoms have been performed in extremely strong and tunable magnetic fields, extending these techniques to a new regime and setting the stage for a variety of cold atom and plasma experiments. Using a superconducting Ioffe-Pritchard trap and an optical molasses, 2.4 x 10(7) atoms were laser cooled to the ...

White-light laser cooling and trapping

SPIE Proceedings, 2001
The basic ideas of the “white-light” laser cooling and trapping are discussed and the applications to atom and ion cooling and trapping are presented. “White-light” cooling allows one to maximise at the same time both the velocity capture range and the cooling rate.

Laser cooling and trapping of ytterbium atoms

Frontiers of Physics in China, 2009
The experiments on the laser cooling and trapping of ytterbium atoms are reported, including the two-dimensional transversal cooling, longitudinal velocity Zeeman deceleration, and a magneto-optical trap with a broadband transition at a wavelength of 399 nm.

Coherent amplification in laser cooling and trapping

Physical Review A, 2006
The optical scattering force, behind Doppler cooling and magneto-optical trapping, may be amplified without incurring additional spontaneous emission by the state-dependent coherent deflection produced by a pulsed or chirped laser field. At some cost in experimental complexity, amplified forces allow efficient cooling on narrow transitions and permit ...
