Abstract

Experiments have conclusively demonstrated coherence properties of Bose-Einstein condensates [BECs] [1] and the radio-frequency [rf] radiation output coupling of BE condensates [2]. Hence, the concept of an atom laser [3 9] based upon a BEC that is output coupled via a rf field stimulated process to produce macroscopic coherent matter waves has been marvelously experimentally demonstrated. Here we explore the nature of the output coupling of atom lasers show that the output coupling can be described as stimulated emission of bosonic atoms using rf radiation from a coupling of atom lasers with the theory of molecular photodissociation is developed. We draw upon these analogies to help explain the various regimes of coupling radiation sources to BECs. We also treat the coupling of a BEC to other spin states that are trapped by the confining fields, and therefore are not outcoupled from the trap.
