A sandwich-like WS2/MoS2/WS2 heterostructure saturable absorber (SA) was prepared with the wet transfer method. Using sandwich-type SA, a passively Q-switched and mode-locked (QML) YVO4/Nd:YVO4/YVO4 laser at 1.06 µm demonstrated. At pump power of 11.5 W, stable QML operation can be achieved, corresponding to maximum repetition rate 10.5 MHz pulse energy 21.9 nJ. Compared previous results obtained in lasers single transition metal disulphide (TMD), higher envelope shorter duration obtained. The prove SA has excellent optical properties for all-solid-state applications.

Abstract 2D van der Waals (vdW) semiconductors attract attention for their unique optoelectronic properties and emerging applications, as they exhibit unexplored phenomena in ultrathin films. Beyond stable excitonic characteristics at room temperature, efforts focus on enhancing light‐matter interactions by integrating hybrid structures due to absolute thinness. Here, a method controlling emission suppressing interlayer charge transfer vdW heterojunctions using plasmonic hybridization is presented. This achieved stacking multilayer (ML)‐GaSe monolayer (1L)‐MoS 2 Ag film. At the edge of this device, Purcell effect significantly enhanced radiative excitons from both GaSe MoS . In contrast, occurrs center absence enhancement, resulting exciton quenching. The work demonstrates potential manipulate between layers through interactions.

Abstract The study of nonlinear optical responses in the mid-infrared (mid-IR) regime is essential for advancing ultrafast mid-IR laser applications. However, effects under excitation are rarely reported due to lack suitable materials. natural van der Waals heterostructure franckeite, known its narrow bandgap and stability air, shows great potential developing devices. We have experimentally demonstrated that layered franckeite exhibits a broadband wavelength-dependent response spectral region. Franckeite nanosheets were prepared using liquid-phase exfoliation method, their was characterized range 3000 nm 5000 nm. exhibit third-order nonlinearities, with absorption refraction coefficients estimated be about 10 −7 cm/W −11 cm 2 /W, respectively.
