TL;DR: In this paper, the authors demonstrate comprehensive studies on graphene oxide and reduced graphene oxide (rGO) based saturable absorbers (SA) for mode-locking of Er-doped fiber lasers.

TL;DR: It has been shown that GO might be successfully used as an efficient SA without the need of its reduction to rGO, and seems to be a good candidate as a cost-effective material for saturable absorbers for Er-doped fiber lasers.

TL;DR: It is experimentally shown that BP exhibits saturable absorption in the 2 μm wavelength range and supports ultrashort pulse generation and might be considered as a universal broadband saturable absorber that could successfully compete with graphene or other low-dimension nanomaterials.

TL;DR: In this article, the authors demonstrate that black phosphorus can serve as a broadband saturable absorber and can be used for ultrashort optical pulse generation with performances similar or even better than currently used graphene or carbon nanotubes.

TL;DR: In this paper, a broadband saturable absorber of black phosphorus was used for ultrashort optical pulse generation, where the mechanically exfoliated ~300 nm thick layers were transferred onto the fiber core and under pulsed excitation at 1560 nm wavelength its transmission increases by 4.4%.
