ABSTRACT
Graphene is the thinnest material in the world with the lowest electrical resistance at room temperature among others. It is highly transparent and a good conductor. Graphene is not only used as new electronic materials but also recognized as novel optoelectronic devices, such as solar cells, transparent touch screens, and saturable absorber (SA). In this chapter, a stable optical pulse generation of graphene-based SA in ultrafast ber laser system is investigated. Two different fabrication processes of graphene samples are reported, which are chemical vapor deposition (CVD) and graphene-mediated SA employing different nano-dispersants.
