چکیده
|
Mode-locked erbium doped fiber laser by using graphene oxide (go) that obtained by oxidation and ultra-sonification process of natural graphite was reported. go produced was dissolved in water and mixed with polyethylene oxide (peo) to form film. when the fabricated go-peo film saturable was employed in the proposed edfl configuration,the laser generates 1.25 ps pulses at a repetition rate of 21.8 mhz with pump input of 70 mw. the stable mode-locking operation was observed within pump input power of 70 mw until 175 mw. soliton-like spectrum was achieved with prominent kelly-sideband and centre wavelength of 1558.6 nm. © 2016 penerbit utm press. all rights reserved.
