    摘要: A method for fabricating an optical fiber coupler device includes a step of tangibly fusing a first outer cladding of a first optical fiber with a second outer cladding of a second optical fiber as a result of pulling and heating the first and second optical fibers at lengths not exceeding 3 mm to form a first region of structurally-integrated with one another first and second optical fibers, and a step of heating a second, neighboring region of these fibers to configure the device to transmit optical power of at least about a hundred Watts and up to at least a kWatt from the input end to the output end with a value of throughput loss not exceeding 0.2 dB.

    摘要: A method of ablating a solid substance within a mammalian body is presented. The method includes generating a superheated zone within the body using a fiber lasing assembly that emits pulses at a pulse repetition rate of 1 kHz to 500 kHz, where each pulse has a wavelength from 1.7 micron to 2.2 micron, a pulse width from 2 ns to 800 ns, and a pulse energy from 0.05 mJ to 2 mJ. The fiber lasing assembly used further includes a seed laser and an amplifier optically connected to the seed laser by an Ho-doped, Tm-doped, or Ho Tm co-doped fiber.

    摘要: An all-fiber optic Faraday rotator and isolator is presented. The device has a multicomponent glass optical fiber having a core having a first doping concentration of 55%-85% (wt./wt.) of a first rare-earth oxide and a cladding having a section doping concentration of 55%-85% (wt./wt.) of a second rare-earth oxide, where the first rare-earth oxide and the second rare earth oxide are one or more of Pr2O3, Nd2O3, Pm2O3, Sm2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, La2O3, Ga2O3, Ce2O3, and Lu2O3, and where the refractive index of the cladding is lower than a refractive index of the core. The fiber optic device further includes multiple magnetic cells each formed to include a bore extending there through, where the fiber is disposed in the bore of one of the magnetic cells.
