Abstract :
A detailed study of supercontinuum (SC) generation in germano-silicate fibers with a femtosecond silica-based all-fiber laser system is performed. We report on more than octave spanning SC in the range 1-2.6 μm pumped at 1.6 μm as well as SC in the range 1.9-3 μm pumped at 2 μm. It is also shown theoretically that with optimal germano-silicate fiber parameters, SC extending beyond 3 μm can be produced effectively.
