We demonstrate that dispersive waves generated by solitons within the small-core features of a photonic crystal fiber cladding can be used to obtain femtosecond pulses tunable over an octave-wide spectral range. The generation process is highly efficient and occurs at the relatively low laser powers available from a simple Ti:sapphire laser oscillator. The described phenomenon is general and will play an important role in other systems where solitons are known to exist.en©2010 The American Physical SocietyJournal article003001878110.1103/PhysRevA.81.0318030002762625000222-s2.0-77949545230165042Light, P.S.
