Graphene saturable absorbers applications in fiber lasers

Abstract Two-dimensional materials are widely used in a variety of fields, such as medical treatment, industrial preparation, machining, etc. In this review, we have made detailed description the development fiber lasers well evolution two-dimensional materials, especially graphene. addition, describe optical properties graphene and its preparations, for instance, chemical exfoliatio, liquid phase exfoliation, electrochemical technique, vapor deposition, supercritical fluid thermal exfoliation. Meanwhile, also summarized several types saturable absorbers like all fiber, D-shaped, deposition. Furthermore, summarize applications based on Finally, take look at future perspectives discuss field optics. It is note worth that will use more heterostructures or gas-solid mixtures to prepare absorbers.
