We use this nonresonant force to deflect I 2 and CS 2 molecules. We trace the direction of molecules in a molecular beam, showing that the molecules that pass near the center of a 1.06-m or 10.6-m laser beam will focus. We predict that Stark shifts on the order of 50 meV can be obtained for all small molecules and atoms while maintaining ionization rates below 10 6 s Ϫ1 . Among the devices that can be based on the nonresonant Stark shift are molecular accelerators and molecular quantum wires.

Pulsed Standing-Wave Mirror for Neutral Atoms and Molecules

“…Atom optical components based on pulsed laser fields will, therefore, not be sensitive to the internal energy-level structure of the particles and, consequently, will also allow manipulation of multilevel atoms and molecules. To date, there exist a few experimental realizations of molecular manipulation with pulsed laser fields [12,13]. Although these examples are still quite scarce, they have been able to demonstrate the great potential of the concept in providing an alternative way to realize components for atom and molecular optics.…”

“…2 Substituting the values of D N ϭ0.5 mm and lϭ85 mm, ⌬v trans init ϭ3.4 m/s. The maximum velocity change during the REMPI processes (⌬v REMPI ) can be estimated from the photoelectron kinetic energy and the momentum conservation law.…”

“…This nonresonant dipole force has been successfully used to control neutral molecules. By focusing intense nanosecond Nd:YAG or CO 2 laser pulses, deflection of molecular beams of simple linear molecules such as I 2 and CS 2 was demonstrated. 1,2 Intense laser fields also have been used to control the molecular orientation.…”

“…By focusing intense nanosecond Nd:YAG or CO 2 laser pulses, deflection of molecular beams of simple linear molecules such as I 2 and CS 2 was demonstrated. 1,2 Intense laser fields also have been used to control the molecular orientation. A theoretical description was given for the pendular motion of molecules about the axis of polarization of an intense laser field, 3 and this alignment effect of molecules was observed by Raman experiments on two intermolecular bonds of a naphthalene trimer.…”
