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： Method for fabricating of all-optical-fiber based optical polarizer devoid of fusing of first and second optical fibers. The method includes a process of forming a substantially adiabatic optical fiber taper by pulling an optical fiber and interrupting this process when an optical power parameter measured at an output of the optical fiber is reduced below a pre-defined threshold as a result of said pulling. An optically-tapered single-mode polarization-maintaining optical fiber element fabricated according to the method and configured as such all-optical-fiber polarizer.

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.
