Query: Bichromatic force on metastable Argon for Atom Trap Trace Analysis   For an efficient performance of Atom Trap Trace Analysis, it is important to
collimate the particles emitted from an effusive source. Their high velocity
limits the interaction time with the cooling laser. Therefore forces beyond the
limits of the scattering force are desirable. The bichromatic force is a
promising candidate for this purpose which is demonstrated here for the first
time on metastable argon-40. The precollimated atoms are detected in one
dimension and the acquired Doppler shift is detected by absorption
spectroscopy. With the experimentally accessible parameters, it was possible to
measure a force three times stronger than the scattering force. Systematic
studies on its dependence on Rabi frequency, phase difference and detuning to
atomic resonance are comparedto the solution of the optical Bloch equations. We
anticipate predictions for a possible application in Atom Trap Trace Analysis
of argon-39 and other noble gas experiments, where a high flux of metastable
atoms is needed.
