Optical phase conjugation (OPC) is of interest for many applications. The generation of squeezed light, phase-conjugate mirrors, optical correlation, and turbulence correction would all benefit from improved OPC performance. Using Zeeman sublevels and cross-circularly polarized light in rubidium vapor, we demonstrate an OPC process that uses very low power (30 mW) but is still very fast (60 ns) and efficient (gain of 20). This process is generic enough to be applicable to almost any resonant medium.

Optical phase conjugation (OPC) is of interest for many applications such as optical resonators, high speed turbulence correction, and the production of the squeezed vacuum state. In the interest of practical implementation of OPC, the simplest method is to produce a phase conjugate mirror (PCM). In the work we have used the PCM as well as the gain associated with the OPC to form a ring laser.
