Query: Four-wave mixing in a ring cavity   We investigate a four-wave mixing process in an N interaction scheme in Rb
vapor placed inside a low-finesse ring cavity. We observe strong amplification
and generation of a probe signal, circulating in the cavity, in the presence of
two strong optical pump fields. We study the variations in probe field gain and
dispersion as functions of experimental parameters with an eye on potential
application of such a system for enhanced rotation measurements. A
density-matrix calculation is performed to model the system, and the
theoretical results are compared to those of the experiment.
