In recent years, 2D layered materials, including graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, and metal‐organic frameworks, have attracted considerable interest due to their potential applications in the fields of physics, chemistry, biology, and energy. Their rise in the field of nonlinear photonics began around 2009 and has become an important research direction. Here, the synthesis techniques, nonlinear optical properties, integration strategies, and device applications of layered materials are reviewed. In terms of nonlinear optical properties, the focus is on saturable absorption and Kerr nonlinearity. On this basis, their applications in various pulsed lasers, including fiber lasers, solid‐state lasers, waveguide lasers, and related nonlinear optical phenomenon, are summarized. In addition, novel optical devices using layered materials, such as optical modulators, optical polarizers, optical switchers, and even all‐optical device, are also involved. It is believed that the development of 2D layered materials in the field of photonics will continue to deepen, thus laying a good foundation for its practical application.

Owing to their extraordinary physical and chemical properties, two-dimensional (2D) materials have aroused extensive attention and have been widely used in photonic and optoelectronic devices, catalytic reactions, and biomedicine. In particular, 2D materials possess a unique bandgap structure and nonlinear optical properties, which can be used as saturable absorbers in ultrafast lasers. Here, we mainly review the top-down and bottom-up methods for preparing 2D materials, such as graphene, topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes. Then, we focus on the ultrafast applications of 2D materials at the typical operating wavelengths of 1, 1.5, 2, and 3 μm. The key parameters and output performance of ultrafast pulsed lasers based on 2D materials are discussed. Furthermore, an outlook regarding the fabrication methods and the development of 2D materials in ultrafast photonics is also presented.

“…TMDs possess a two-dimensional (2D) layered structure bonding via Van der Waals' force between the atomic layers. When the bulk TMDs were exfoliated to single/few-layer nanosheets, novel physical and chemical properties emerged in the atomic nanosheets [5,6] , which endowed them with intriguing functionality that cannot be found in the bulk counterpart [7] . Among the TMDs, the VIB group metal dichalcogenides MoS 2 [7][8][9] and WS 2 nanosheets [10][11][12] were the most widely explored in optical limiting performances for high-energy lasers due to the low initial threshold, tunable nonlinear optics (NLO) responses, and unique absorption ways dependent on the number of layers.…”

The optical limiting performances of few-layer transitional metal dichalcogenides (TMDs) nanosheets in the VB group (VS 2 , VSe 2 , NbS 2 , NbSe 2 , TaS 2 , and TaSe 2 ) were systematically investigated for the first time, to the best of our knowledge. It was found that these TMDs nanosheets showed a normalized transmittance in the range of 20%-40% at the input energy of 1.28 GW=cm 2 . Ultralow initial threshold F S (0.05-0.10 J=cm 2 ) and optical limiting threshold F OL (0.82-2.23 J=cm 2 ) were achieved in the TMDs nanosheets, which surpassed most of the optical limiting materials. This work showed the potential of TMDs beyond MoS 2 in optical limiting field.
