Abstract
We study the second-order nonlinear optical properties of several 2D materials through second harmonic generation (SHG) and sum frequency generation (SFG). SHG signals from 2D transition metal dichalcogenides (TMD) pumped at multiple fundamental wavelengths are measured and compared with theoretical analysis. We also use polarization-resolved second harmonic generation to characterize 2D materials and explore their biological applications. Using a narrow-band femtosecond laser beam and a supercontinuum, we measure the SFG of TMDs to characterize their second-order nonlinear susceptibility over a range of wavelengths.
