摘要

Mechanically exfoliated (ME) and chemical vapor deposition (CVD) MoS<sub>2</sub> monolayers have been extensively studied, but the large differences of nonlinear optical performance between them have never been clarified. Here, we prepared MoS<sub>2</sub> monolayers using ME and CVD methods and investigated the two-photon absorption (TPA) response and its saturation. We found TPA coefficient of ME monolayer was about (1.88±0.21)×10<sup>3</sup> cm/GW, nearly two times of CVD one, (1.04±0.15)×10<sup>3</sup> cm/GW. Furthermore, we simulated and compared the TPA-induced optical pulse modulation in multilayer cascaded structures, which is instructive and meaningful for the design of optical devices such as beam shaper, optical limiter.
