Abstract
To compensate the Doppler shift in the laser cooling process, two methods were developed:frequency chirping,1 which tunes the laser frequency rapidly, and a spatially varying magnetic field,2 which tunes The atomic energy level. An alternative approach is to use laser light with a continuous spectrum (white light).3,4 Using only a counterpropagating white-light beam will decelerate the atoms in the beam, hut it will not yield a large velocity compression.4,5 To achieve significant cooling, Hoffnagle5 proposed the use of an additional single-frequency laser beam, copropagating with the atomic beam, to counterbalance the nonresonant scattering force from the Lorentzian tail of the atomic transition.
