摘要
A method and apparatus for launching optical pump signals into a disordered gain medium at two points thereby producing a narrow line-width random fiber laser within the disordered gain medium. The optical pump signals are propagated in a direction through the disordered gain medium towards one another. The apparatus may comprise an optical gain fiber having a first end configured to receive a first fiber pump signal and a second end configured to receive a second fiber pump signal such that the first fiber pump signal and the second fiber pump signal propagate within the optical gain fiber in a direction towards one another. An optical loss device is coupled to the optical gain fiber, wherein the optical loss device isolates a narrow line-width random fiber laser signal from a signal generated within the optical gain fiber.
