Over the past four years, there has been a surge of activity in the supercontinuum field since the introduction of various types of microstructure fibers. The main reason for this great interest worldwide is the low femtosecond pulse energies (~ 1nJ) required to generate the supercontinuum. The pulses from femtosecond oscillators can conveniently be used to produce supercontinuum. The microstructure fibers provide a micron to submicron size guide over a long distance for a femtosecond pulse to travel along. In comparison to supercontinuum generated in bulk media, there is a limited interaction length,~ 5cm for supercontinuum. In addition, self-focusing (beam breakup) in bulk requires larger energies in the 100mJ to mJ range for supercontinuum production. Also, the fibers have unique dispersion characteristics which provide for zero dispersion, and anomalous dispersion (negative) regions to keep the …
