Femtosecond ytterbium fiber laser with photonic crystal fiber for dispersion control

摘要

A photonic-crystal fiber provides dispersion compensation in a soliton fiber laser. The anomalous dispersion provided by the photonic-crystal fiber permits construction of a femtosecond fiber laser at 1 mum 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 mum.
