Abstract
In this work we present our results on supercontinuum (SC) generation using 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 (6 cm) is pumped by a femtosecond fiber laser system, delivering 540 fs pulses at 60 MHz repetition rate and 2.75 W of maximum average power. This compact and cost-effective system allows to generate supercontinuum spanning from 900 to 2400 nm.
