摘要： A method and apparatus for producing single mode random fiber ring laser by inducing random distributed feedback in a short section of the fiber ring to thereby enable single mode lasing while reducing frequency jitter and relative intensity noise. The random distributed feedback maybe achieved through deep refractive index modulation at a series of randomly distributed laser-irradiated points inscribed along the length of the induced random distributed feedback fiber. The laser-processed random distributed feedback fiber maybe incorporated into the fiber ring in conjunction with a variable optical attenuator and band pass optical filter for enhancing the single mode operation.

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.
