We describe a simple and robust method of creating an efficient large-angle adiabatic passage beamsplitter that does not require the light fields to be pulsed. We present simulations that show momentum splittings of , where more than 60% of the atoms in the initial distribution are in the final momentum peaks at .

The effectiveness of coherent adiabatic passage in atomic systems with a closed interaction contour was studied. The dependence of coherent adiabatic passage on the algebraic sum of initial exciting field phases was demonstrated for the example of a double Λ-system of atomic levels. The conditions that should be met by interaction parameters for the occurrence of effective coherent adiabatic passage at various atomic contour phases were determined.
