abstract

The frequency-doubled radiation of an Erbium-doped fiber laser is used for supercontinuum generation in a small-core microstructured fiber with two zero-dispersion wavelengths. Average powers up to 49 mW are launched into the highly nonlinear photonic-crystal fiber. The generated supercontinuum shows a short-wavelength peak centered around 670 nm and a long-wavelength peak centered around 1100 nm. More than 35 mW is contained in the short-wavelength peak. We use the anomalous dispersion of a SF10 prism compressor to compress the short-wavelength peak of the spectrum. The compressed pulse has a central wavelength of 670 nm and a duration of 27 fs.
