E. Arimondo, VELOCITY-SELECTIVE COHERENT POPULATION TRAPPING IN CESIUM ATOMS, Philosophical transactions-Royal Society of London. Physical sciences and engineering, 355(1733), 1997, pp. 2397-2399
The extension to high angular momentum transitions of laser cooling be
low the recoil limit based on velocity-selective coherent population t
rapping (VSCPT) is explored. An efficient VSCPT can be realized only b
y applying a compensation of the kinetic energy mismatch between the c
omponents of the superposition wavefunction and introducing repumping
on the hyperfine transitions. Theoretical and experimental progress fo
r VSCPT on caesium atoms is discussed.
