Query: Making ultracold molecules in a two color pump-dump photoassociation
  scheme using chirped pulses   This theoretical paper investigates the formation of ground state molecules
from ultracold cesium atoms in a two-color scheme. Following previous work on
photoassociation with chirped picosecond pulses [Luc-Koenig et al., Phys. Rev.
A {\bf 70}, 033414 (2004)], we investigate stabilization by a second (dump)
pulse. By appropriately choosing the dump pulse parameters and time delay with
respect to the photoassociation pulse, we show that a large number of deeply
bound molecules are created in the ground triplet state. We discuss (i)
broad-bandwidth dump pulses which maximize the probability to form molecules
while creating a broad vibrational distribution as well as (ii)
narrow-bandwidth pulses populating a single vibrational ground state level,
bound by 113 cm$^{-1}$. The use of chirped pulses makes the two-color scheme
robust, simple and efficient.
