2D Saturable Absorbers for Fibre Lasers

Abstract: Two-dimensional (2D) nanomaterials are an emergent and promising platform for future photonic and optoelectronic applications. Here, we review recent progress demonstrating the application of 2D nanomaterials as versatile, wideband saturable absorbers for Q-switching and mode-locking fibre lasers. We focus specifically on the family of few-layer transition metal dichalcogenides, including MoS 2 , MoSe 2 and WS 2 .

“…[16,17] The enhancement is attributed to the combination of nonlinearm echanism and the photoinduced electron transfer or energy transfer betweenc hromospheres and the CNT moiety. [22][23][24] Compared to graphene with zero-band gap and BP with easy oxidation and deliquenscence, MoS 2 is semiconducting and has good chemical stability.I th as been confirmed that MoS 2 nanosheets have excellent third-order NLO performance over ab road wavelength range from visible( Vis) to near infrared (NIR) region with versatile optical mechanisms, such as saturable absorption (SA), two-photon absorption (TPA), and nonlinear scattering (NLS). [18][19][20][21] MoS 2 ,o ne of the typical TMDs, has al ayered structure formed by as tack of sandwiched S-Mo-S planesh eld together by weak van der Waalsi nteractions.…”

“…A few years later, the Q-switched laser was discovered by using colored glass filter and dyes onto ruby laser configuration [1]. Since then, the materials used has evolved from semiconductor saturable absorber mirror (SESAM) to nanomaterials such as quantum dots, carbon nanotubes, graphene, transition metal dichalcogenides (TMDs), black phosphorous (BP) and topological insulators (TIs) [2]. Topological insulators in bulk state have an insulating energy gaps whether in two or three dimensions but the sample boundary were protected by time-reversal symmetry at the surface state or gapless edge [3].…”
