Atomic beam splitter based on multiple adiabatic passage in the optical interference pattern

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 80 \hbar k, where more than 60% of the atoms in the initial distribution are in the final momentum peaks at +/- 40 \hbar k.
