We experimentally deposited a graphene oxide(GO) onto an end face of the optical fiber with the new method by applying electrical arc and pulse laser drilling to GO using commercial fusion splicer and laser ring cavity. We demonstrate a Q-switched Er-doped fiber laser (EDFL) using GO thin film deposited by proposed method as a saturable absorber (SA). We successfully generated stable passively Q-switched EDFL in both C- and L-band using different GO SA without adjusting the optical gain. Detailed GO film deposition method at end face of the optical fiber using electrical arc and pulse laser drilling are discussed. Our proposed deposition method with electrical deposition method and pulse laser drilling might be applied to make a SA with other similar two-dimensional materials.
