We report the generation of a broadband super- continuum with a CW Yb fiber laser and a PCF. The spectrum extends toward short wavelengths through efficient dispersive wave generation.
Supercontinua spanning 320 -2400 nm have been generated in long photonic-crystal- fiber tapers. Total average powers of over 3.5 W and spectral-power-densities in the blue of over 5 mW/nm are demonstrated. Use as a broadly-tunable pulse source is proposed.

We have fabricated a photonic crystal fiber with a continuously decreasing zero-dispersion wavelength along its length. It has been used to generate an ultraviolet-extended supercontinuum from a nanosecond pump source at 1.064 mum
Amorphous N- or Ge-doped H:SiO2 films deposited on silica by the matrix distributed electron cyclotron resonance-PECVD method were irradiated by an electron-beam with different doses in order to pole the material and induce second harmonic generation (SHG). SHG was measured using the Maker-fringe method. When irradiated at an acceleration voltage of 25 kV, an incident current of 5 nA during 480 s,...
