✦ Synopsis
In order to achieve the phase-sensitive probe gain
without population inversion, we investigate a four-level atomic
system, where the probe field is controlled by a three-level
closed loop subsystem. In the case of three-photon resonance,
large steady-state inversionless probe gain can be obtained. Owing
to the quantum interference, the probe gain is sensitive to the
relative phase of the three-level closed loop subsystem. The
intensities of the fields of the three-level closed loop subsystem
are also important factors that can result in different gain
behaviors of the probe field.
