OPTICAL PULSE SHAPER, OPTICAL PULSE LIGHT SOURCE, SUPER CONTINUUM LIGHT GENERATOR AND SUPER CONTINUUM LIGHT GENERATING METHOD

摘要

A CPF type optical pulse shaper in which the number of stages is decreased by enhancing compression efficiency sharply per one stage of CPF while sustaining high quality of output pulse, and multiplicity can be enhanced by obtaining such an output pulse as both the time waveform and the frequency waveform are Gaussian type. In place of zero dispersion HNLF constituting a conventional CPF, a normal dispersion HNLF is used. Furthermore, the number of fused fibers is decreased and propagation loss of the CPF is reduced by enhancing compression efficiency.
