Few-layer MoS₂ saturable absorbers for short-pulse laser technology: Current status and future perspectives [Invited]

Few-layer molybdenum disulfide (MoS₂) is emerging as a promising quasi-two-dimensional material for photonics and optoelectronics, further extending the library of suitable layered nanomaterials with exceptional optical properties for use in saturable absorber devices that enable short-pulse generation in laser systems. In this work, we catalog and review the nonlinear optical properties of few-layer MoS₂, summarize recent progress in processing and integration into saturable absorber devices, and comment on the current status and future perspectives of MoS₂-based pulsed lasers.
