Abstract：

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.
