【 摘 要 】

A key enabler in the mode-locked fiber lasers has been the discovery of novel saturable absorbers (SA) such as carbon nanotubes (CNT) and graphene. We demonstrate chemical vapor deposition (CVD)-graphene on nickel (Ni) transferred onto optical fibers preserves its nonlinearity. The influence of the temperature on the growth of graphene was explored by Raman spectra, scanning electron microscope (SEM) and atomic force microscope (AFM), respectively. The results show the temperature will affect the thickness and surface uniformity of graphene on Ni film. Besides, the mechanism of CVD process and the saturable absorption property of the graphene are illustrated, respectively.
