Efficient Visible Continuum Generation In Air-Silica Microstructure Optical Fibers With Anomalous Dispersion at 800nm

We demonstrate for the first time the efficient generation of 1000-nm-broad single-mode continuum by propagating pulses of 100-fs duration and kilowatt peak powers in an air-silica microstructure optical fiber designed to have net anomalous dispersion at 800 nm.
