| Abstract: | A graphene-PVA film is fabricated by using polyvinyl alcohol(PVA),which provides excellent mechanical property and easy operation.Raman spectra of the graphene-PVA film and graphene sheets are measured,which show that the spectra have the same characteristics.The passively mode-lock Er-doped fiber laser with graphene-PVA film as saturable absorber is made,which produces the mode-locked pulses with duration of 10.29 ps,peak wavelength of 1532.75 nm,and repetition rate of 8.7 MHz. |
