Output coupling for an atom laser by state change
G. M. Moy, C. M. Savage
Abstract
We calculate the spectrum of a beam of atoms output from a single mode atomic cavity. The output coupling uses an internal state change to an untrapped state. We present an analytical solution for the output energy spectrum from a broadband coupler of this type. An example of such an output coupler, which we discuss in detail uses a Raman transition to produce a non-trapped state.
