(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 …
