Three-cascaded 1407-nm Raman laser based on phosphorus-doped silica fiber.
We report a laser-diode-pumped 1407-nm Raman fiber laser with an output power of 1 W. In this three-cascaded cw Raman laser, based on a single active phosphorus-doped silica fiber, for the first time to the authors' knowledge successive generation of Stokes components of essentially different frequency shifts (1330 and 490cm(-1)) has been realized. These Stokes components are associated with bo...
متن کاملGeneration of high energy, 30 fs pulses at 527 nm by hollow-fiber compression technique.
The compression of 300-fs-long, chirp-free laser pulses at 527 nm down to 30 fs is reported. The laser pulses, originated from a frequency-doubled, mode-locked Nd:glass laser, were compressed by a 0.7-m-long, 150-microm-bore-diameter, argon-filled hollow fiber, and a pair of SF10 prisms with a final energy of 160 microJ. These are the shortest, high energy pulses ever produced by direct pulse c...
متن کاملPolarization maintaining, very-large-mode area, Er fiber amplifier for high energy pulses at 1572.3 nm
We demonstrate the first polarization maintaining, very-large-mode-area Er-doped fiber amplifier with ~1000 μm 2 effective area. The amplifier is core pumped by a Raman fiber laser and is used to generate single frequency one microsecond pulses with pulse energy of 368 μJ, M 2 of 1.1, and polarization extinction > 20 dB. The amplifier operates at 1572.3 nm, a wavelength useful for trace atmosph...
متن کاملEnergy transfer up-conversion in Tm3+-doped silica fiber
A study of the mechanisms responsible for the infra-red to near infra-red up-conversion in thulium doped silica fibres is presented. Up-conversion luminescence was observed from the H4 level of Tm under 1586 nm pumping into the F4 level. The quadratic dependence of the up-conversion luminescence at 800 nm on the 1800 nm luminescence from the F4 level confirms that the H4 level is populated by a...
متن کاملHigh-efficiency fiber laser at 1018 nm using Yb-doped phosphosilicate fiber.
A high-efficiency fiber laser at 1018 nm using homemade Yb-doped phosphosilicate fiber is demonstrated. The fiber shows blueshifted emission spectrum compared to Yb-doped aluminosilicate fiber, and is considered favorable for the short wavelength Yb-doped fiber laser. With a 7 m gain fiber, up to 22.8 W output at 1018 nm is achieved with an optical efficiency of 53%. The amplified spontaneous e...
