Graphene saturable absorber mirror (SAM) was successfully fabricated by transferring large-size graphene flake on dielectric coating mirror. The graphene transferred on the mirror was tested by Raman spectrum measurement and scanning electron microscope imaging. With the graphene SAM, passive Q-swit...
