    Super-continuous spectrum in sapphire fiber acted by femto-second lasers is researched. A femto-second laser with 50 fs pulse width is chosen as a pumping light source and a 9 cm sapphire fiber as nonlinear medium. The super-continuous light sources in Infrared and visible band can be obtained at sapphire fiber output terminal when laser center wavelength is 1 200 nm, 1 300 nm, 1 400 nm and 1 500 nm respectively. Semiconductor saturable absorber mirror (SESAM) is added to experimental devices to get better super-continuous light source output in visible band. A resonator is made up of fiber terminal surface and SESAM. And multi-acted fiber is realized by SESAM feedback. The results show that 460~780 nm flat and stable super-continuous light source output in visible band is obtained.
