  We present a comprehensive study of dispersion managed ultrashort-pulse
generation in Nd-doped polarization maintaining all-fiber laser at a 920 nm
wavelength. We implement a linear laser scheme with a chirped fiber Bragg
grating (CFBG) serving as a semitransparent mirror and semiconductor saturable
absorber mirror (SESAM) as a mode-locker and as a second non-transparent
mirror. Complete 1064 nm emission filtering is ensured by 920/1064 wavelength
division multiplexer. The dispersion compensation by CFBG was sufficient to
reach anomalous net dispersion in the shortest laser scheme allowing us to
investigate mode-locking regimes in the -0.05 ps 2 - 0.24 ps 2 net dispersion
range by varying the length of the passive fiber. With this approach we
demonstrate high order harmonic mode-locking at dispersion closer to zero and
large energy span near-parabolic shape single pulse operation in anomalous
dispersion regime. The investigation is supported by numerical simulations used
to optimize the laser resonator design and to investigate intracavity pulse
evolution.
