Description/Abstract

Atom interferometers require atom mirrors and beam-splitters that can maintain high fidelity even when experimental parameters vary from the ideal. We address the use of chirped laser pulses to provide such elements via rapid adiabatic passage, and present a prescription for practical pulses that offer controlled adiabaticity throughout. Full- and half-adiabatic pulses, providing mirrors and beam-splitters respectively, are derived, and the latter examined for robustness and suitability for experimental implementations.
