Abstract
The generation of ultra broadband supercontinuum light from microstructured fibers and tapered standard fibers offers many new opportunities for significant new developments in areas such as spectroscopy1 and metrology.2 To date, spectra have been reported spanning from 390-1600 nm using microstructured fiber,’ and from 375–1500 nm4 using tapered fiber, however there remains strong interest in extending the achievable bandwidths still further, particularly towards the ultra-violet (UV) regions of the spectrum. Here using UV transmitting pure silica holey fiber we report strong UV generation at a peak wavelength of 350 nm, accompanied by supercontinuum generation out to at least 1800 nm. We believe that this is the first time that the generation of UV wavelengths. below 300 nm has been demonstrated from a fiber device.
