Progress towards pulse sequence engineering for large momentum transfer in hot helium beam

The strength of optical forces on atoms derives from the rate of exchange of momentum between light and atoms. In previous research, we describe the use of periodic Adiabatic Rapid Passage (ARP) sequences to increase both the excitation and emission rates, and thereby strengthen the optical force to F_ARP » F_rad Ξ hkγ/2. In the recent progress we compared adiabatic sequential pulse with the diabetic sequential pulse designed from floquet atom optics [1] and shortcut to adiabaticity[2] when applied in hot atomic beam source and investigate of the connection between two pulse design methods.
