Nonlinear Optics

Surfaces and interfaces are of great importance since many processes are controlled by interfacial properties. Accessing buried interfaces is, however, particularly challenging since many techniques are not interfacial specific or cannot be applied under technical relevant conditions.

We apply nonlinear optical spectroscopy such as second-harmonic generation (SHG), hyper-Rayleigh scattering (HRS) and sum-frequency generation (SFG) as highly interface selective probes for studies of particle surfaces and interfaces.
