In this work we present results on supercontinuum (SC) generation in a photonic crystal fiber (PCF) fabricated from lead-bismuth-gallium-oxide glass (PBG-08). Due to high refractive index, high nonlinearity and high transmittance, the PBG-08 glass-based fibers seem to be excellent media for broad supercontinuum generation in the infrared spectral region. In our experiment, a short-length piece of PCF (5-6 cm) is pumped by a femtosecond chirped pulse amplification (CPA) setup, which may be seeded by two different fiber-based oscillators. This compact and cost-effective system allows to generate SC spanning from 900 to 2400 nm. The paper describes in detail the fabrication process of the fiber, as well as the SC generation results.
