It was shown that not only wide range soliton wavelength tuning but also soliton pulse width variation could be obtained in the fiber lasers. Our results show that the graphene mode locked erbium-doped fiber lasers provide a compact, user friendly and low cost wavelength tunable ultrashort pulse source.

• I have started researching on the Graphite powder by HOPG method separating as a single layer graphite for Electronics Applications like capacitor., can u suggestion any other method for synthesis graphite to graphene but without CVD process...
