Abstract:
A graphene-based saturable absorber device (22) suitable for use in a ring-cavity fiber laser (200) or a linear-cavity fiber laser (300) is disclosed. The saturable absorber device includes an optical element (10) and a graphene-based saturable absorber material (18) supported by the optical element and comprising at least one of graphene, a graphene derivative and functionalized graphene. An examplary optical element is an optical fiber having an end facet (14) that supports the saturable absorber material. Various forms of the graphene-based saturable absorber materials and methods of forming same are also disclosed.
