## Abstract The generation and stable propagation of ultrashort optical pulses tend to be limited by accumulation of excessive nonlinear phase shifts. The limitations are particularly challenging in fiberβbased devices, and as a result, shortβpulse fiber lasers have lagged behind bulk solidβstate l
Soliton self-frequency shift in a highly nonlinear photonic-crystal fiber is shown to enable an efficient wavelength conversion of 100-fs 70-MHz output of a solid-state ytterbium laser, allowing the generation of sub-100-fs laser pulses with a central wavelength tunable from 1060 to 1400 nm. In the
