Since it was isolated in 2014 [1], graphene has attracted interest in many areas of science and technology due to its superlative properties. From the point of view of the interaction of light with matter, and specifically the aspects of light absorption, the phenomenon involving the saturation of the absorption has been explored by several groups. However, graphene is not alone, it is in fact the best-known and most studied material in a class with hundreds of two-dimensional materials whose properties have been much explored recently.

We will present the main advances we have obtained in the use of this new class of two-dimensional materials (such as graphene, graphene oxide (GO), reduced graphene oxide (r-GO), exfoliated graphite, rhenium disulfide (ReS2) and etc…)[2-5] to obtain ultrashort pulses in cavity lasers in the geometry of fiber. In particular, we focused on fiber lasers with Erbium as the active element due to the fact that its emission at 1550 nm is centered on the conventional C-band in optical communications.
