Phase-sensitive atom laser: phase noise quenching

Summary form only given. We present, a fully quantum-mechanical model for a quasi-CW phase-sensitive atom laser produced from a Bose-Einstein condensate (BEC) atomic source (reservoir). As a particular realization of our model, we consider the f=1 ground-state multiplet of /sup 23/Na atoms in a harmonic optical trap. The reservoir BEC state, taken to be the spin-0 state, contains a very large number of atoms N, while the other trapped hyperfine states m/sub f/=1 as well as m/sub f/=-1 (the lasing states) are assumed to be initially empty. Pumping from the source BEC state to the lasing BEC states is implemented via two-photon Raman transitions which are driven by an external classical driving field and the quantized field of a single-mode polarization-selective optical cavity.
