    摘要: The invention features a fiber that includes an optical fiber (110) containing a gain medium having a Raman active material with a Raman gain spectrum. The optical fiber is configured to receive energy at a wavelength λp. The fiber also includes at least three pairs of reflectors (120, 125, 150, 130, 160) disposed in the optical fiber. Each pair of reflectors forms a resonance cavity (140) with a resonance frequency.

    摘要: Fiber laser systems. One system comprises a pump energy source, a first fiber and a WDM for transferring pump energy from the first fiber to a second fiber that comprises a grating for reflecting energy at a predetermined wavelength. The first fiber is devoid of a grating substantially reflecting energy of the predetermined wavelength. In another embodiment, a system includes a pump energy source and a fiber comprising a loop-shaped portion, a first non loop-shaped portion comprising a grating for reflecting pump energy, and a second non loop-shaped portion comprising a grating for reflecting a Stoke shifted wavelength. In another embodiment, a system includes a pump energy source and a fiber comprising a first pair of gratings for reflecting energy at a first wavelength corresponding to a first order Stoke shift, a second pair of gratings for reflecting energy at a second wavelength corresponding to a Stoke shift order greater than one, and a third pair of gratings for reflecting energy having a Stoke shift order greater than that of the second wavelength. No grating of the third pair is located between gratings of the second pair.
