Ultrafast Yb-Doped Fiber Laser Using Few Layers of PdS₂ Saturable Absorber.

ABSTRACT: Two-dimensional (2D) transition metal dichalcogenide (TMD) materials have exceptional optoelectronic and structural properties, which allow them to be utilized in several significant applications in energy, catalyst, and high-performance optoelectronic devices. Among other properties, the nonlinear optical properties are gaining much attention in the research field. In this work, a unique pentagonal TMD material, palladium disulfide (PdS₂), is employed as a saturable absorber (SA) in an ytterbium-doped fiber (YDF) laser cavity and mode-locked laser pulse is generated. At first, liquid phase exfoliation is performed to prepare PdS₂ nanoflakes. Afterward, the PdS₂-nanoflakes solution was incorporated in the side-polished fiber (SPF) to form SPF-based PdS
