We report a 50-fold fiber-grating pulse compression in the near-infrared region. 100 ps (FWHM) pulses from a mode-locked neodymium:yttrium aluminum garnet laser operated at 1.319 μm have been compressed into 2 ps pulses by using a 2-km dispersion-shifted fiber and a grating pair separated by 2.41 m in a double-pass configuration. The novel feature of this demonstration is the use of dispersion-shifted fiber (zero-dispersion wavelength at 1.59 μm) for producing a linear chirp over most of the pulse and, thus, almost all the input power appears in the compressed pulse.
