Publisher Summary This chapter describes some of the experiments in atom optics in which laser fields play a predominant role in the manipulation of the center-of-mass motion of atoms. The chapter reviews the basic ingredients of the mechanical effects of atom–laser interactions. It discusses focusing of atoms using “lenses of light,” and presents field configurations that realize achromatic lenses. It outlines the experimental activities in atom lithography and discusses the basics of “nonclassical” atom optics. The chapter further elaborates entanglement of photons and atoms, and presents experimental results that demonstrate the underlying principle of a Heisenberg microscope. It also discusses the first results of the atom–photon correlation experiments, which should ultimately lead to the realization of Greenberger-Horne-Zeilinger (GHZ) entangled states. The chapter also addresses the effects of the quantum degeneracy, presenting a scheme for a laserlike source of atoms, and where the experimental efforts to build resonators and waveguides for atoms are outlined. |
