Abstract

We present a comprehensive study of second harmonic generation (SHG) and third harmonic generation (THG) from single- and few-layer transition metal dichalcogenides (MoS₂, MoSe₂, WS₂ and WSe₂). We measure SHG and THG from these materials with a multiphoton microscope with linearly polarized 1560 nm femtosecond excitation. We find that SHG from monolayer MoSe₂ under 1560 nm excitation is more than four times stronger than that of other studied materials.
