Abstract

Experiments toward colder and denser neutral atomic vapors in traps have made rapid progress in the past few years. With the novel techniques in optical cooling and magnetic traps, it is now possible to produce atomic samples with temperatures dose to nanokelvins. Such ultracold atomic samples have stimulated new interest in laser cooling and atom optics. In this paper we propose a scheme in which a spatial alomic wave packet from an ultracold atomic source is loaded into a traveling-wave laser beam with a Gaussian intensity profile. The ullracold atomic source is assumed to be composed of identical bosonic atoms.
