Giant Two-Photon Absorption in Monolayer MoS2
Yuanxin Li, Ningning Dong, Saifeng Zhang +5
Strong two-photon absorption (TPA) in monolayer MoS2 is demonstrated in contrast to saturable absorption (SA) in multilayer MoS2 under the excitation of femtosecond laser pulses in…
Direct Observationof DegenerateTwo-Photon Absorption and Its Saturation in WS2 and MoS2 Monolayer and Few-Layer Films
Saifeng Zhang, Ningning Dong, Niall McEvoy +10
The optical nonlinearity of WS2, MoS2 monolayer and few-layer films was investigated using the Z-scan technique with femtosecond pulses from the visible to the near infrared. The d…
Optical Limiting and Theoretical Modelling of Layered Transition Metal Dichalcogenide Nanosheets
Ningning Dong, Yuanxin Li, Yanyan Feng +6
Nonlinear optical property of transition metal dichalcogenide (TMDC) nanosheet dispersions, including MoS2, MoSe2, WS2, and WSe2, was performed by using Z-scan technique with ns pu…
