We have experimentally investigated the pulse dynamics of a PML YDFL in operation at net normal dispersion region. Without insertion of slit, the spectrum of NLP reveal broad bandwdith and the double scale femto/pico-second IAC trace. After insertion of slit inside laser cavity, we demonstrate the operation state of YDFL can be switched from DSs to the NLP by the pump power. Through the spatial tuning of the slit, the operation state and central wavelength can also be controlled in the near future that show the abundant dynamic of the PMLYDFL.
