Abstract: We demonstrate the use of photonic-crystal fiber for disper-
pensation in a soliton fiber laser. The anomalous dispersion
provided by the photonic-crystal fiber enables us to construct a fem-
tosecond fiber laser at 1 µm wavelength without prisms or diffraction
gratings. The laser produces ∼100-fs pulses with 1 nJ energy, and is a
major step toward environmentally-stable all-fiber devices at 1 µm.
