High-Speed Imaging of Second-Harmonic Generation in MoS<sub>2</sub> Bilayer under Femtosecond Laser Ablation

High-Speed Imaging of Second-Harmonic Generation in MoS<sub>2</sub> Bilayer under Femtosecond Laser Ablation

We report an in situ characterization of transition-metal dichalcogenide (TMD) monolayers and twisted bilayers using a high-speed second-harmonic generation (SHG) imaging technique. High-frequency laser modulation and galvano scanning in the SHG imaging enabled a rapid identification of the crystall...
