| Abstract: | Optical second harmonic generation (SHG) and sum frequency generation (SFG) are second-order nonlinear optical responses of matter. When two intense light pulses with photon energies ℏω1 and ℏω2 enter a solid, a new light pulses with photon energy ℏω1+ℏω2 can be generated. This phenomenon is called SHG when ω1=ω2, and SFG when ω1≠ω2. Within the electric dipole approximation, SHG and SFG have a unique property of being allowed for media without spatial inversion symmetry. In this paper, I describe examples of analyses of a photocatalyst material titanium dioxide (TiO2), metal nanowire arrays,
hydrogen-terminated Si(111) surfaces, and chiral biomaterials, by SHG/SFG spectroscopic or microscopic observation. I will pay special attention to a viewpoint of inversion symmetry breaking causing SHG or SFG in each material. |
