The dispersion-managed passively mode-locked Yb-doped fiber laser is designed, using negative group velocity dispersion characteristics of photonic crystal fiber at 1 μm wavelength. The net group velocity dispersion of the fiber laser is normal. Larger pulse energy can be generated from this laser. The generation of the dissipative dispersion-managed soliton is studied through numerical simulation. The amplitude modulation of the saturated absorber and the gain dispersion of the Yb-doped fiber play significant roles in the formation of the soliton. The effects of the positive and negative dispersion elements on the pulse width and spectrum width are analyzed. The time bandwidth product increases gradually with the net group velocity dispersion value decreasing. The shortest pulse of 90 fs width is obtained through further compression.
