By application of laser cooling and atom trapping techniques, considerable progress is being made in the manipulation and control of atomic gases. Using these techniques, Atom Optics attempts to shape atom trajectories in a manner analogous to the way light is controlled by mirrors, lenses, and gratings. Atomic gas Bose-Einstein condensates will contribute to atom optics much like lasers have contributed to applications using photons. Atom Nanolithography is the application of Atom Optics to control, on the nanoscale, the surface deposition of atoms. Experiments using chromium atoms have been conducted to explore the limits of this new form of lithography.
