We　experimentally　demonstrate　a　cascaded　Raman　scattering　continuum,　utilizing　a　compact　mode-locked　Yb-doped　fiber　laser　based　on　a　nonlinear　polarization　rotation　technique　in　the　all　normal　dispersion　regime.　There　is　no　physical　filter　or　polarization　controller　in　the　oscillator,　and　a　different　mode-locked　operation　is　achieved,　corresponding　to　the　extra　fiber　location　in　the　oscillator.　The　broadband　spectrum　generation　owes　to　the　enhanced　stimulated　Raman　scattering　progress.　The　maximum　output　average　power　and　peak　power　are　14.75　nJ　and　18.0　W,　and　the　short　coherence　light　is　suited　for　optical　coherence　tomography.
