Gp. Djotyan et al., MANIPULATION OF 2-LEVEL QUANTUM-SYSTEMS WITH NARROW TRANSITION LINES BY SHORT LINEARLY POLARIZED FREQUENCY-CHIRPED LASER-PULSES, Journal of the Optical Society of America. B, Optical physics, 13(8), 1996, pp. 1697-1705
We propose and investigate theoretically a novel scheme for transient
slowing and cooling of two-level quantum systems with narrow transitio
n linewidths by a sequence of counterpropagating, short, linearly pola
rized laser pulses with special frequency chirping. Both internal degr
ees of freedom and the motion of the center of mass of quantum systems
are considered quantum mechanically. interaction with a large number
of laser pulses during the decay time permits a drastic decrease in th
e cooling time of such systems. (C) 1996 Optical Society of America.
