ABSTRACT:
A method is disclosed for establishing an optical link between two lasers via an optical fiber by directing the output from one laser through an optical fiber and into a second laser and vice vera. Before insertion into the lasers, the output from the respective fibers is phase conjugated in a double phase conjugate mirror. Thus, the disclosed method and apparatus provide a combination of fiber optics, used to transport the light from the lasers, and optical phase conjugation, used to compensate for fiber-induced distortions.
