  • Optical fibre laser pump source for fibre amplifiers
    Patent number: 5710786
    Abstract: Apparatus for generating laser light having a wavelength in the range of about 1012 to 1022 nm comprising a double clad optical fiber having a core doped with triply ionised ytterbium ions, a source of laser light emitting at a wavelength of about 800 to 1070 nm and coupled to launch the fight into the fiber, and fiber Bragg gratings written into the core region of the optical fiber so as to provide optical discrimination of the emission centered in the range of about 1012 to 1022 nm.
