When nonlinear optical materials are exposed to intense laser radiation, processes are triggered that can generate light with different wavelengths. Coupled mode equations for three wave The present study gives a brief introduction to sum-frequency generation (SFG) vibrational spectroscopy with an overview of the role of second-order nonlinear optical process. As with any optical phenomenon in nonlinear optics, this can only occur under conditions where: the light is interacting with matter, that lacks centrosymmetry (for example, surfaces and interfaces); the light has a very high intensity (typically from a pulsed laser). Beginning with an overview of the historical context, and introductions to the basic theory of nonlinear optics and surface sum-frequency generation, topics covered include discussion of different Within nonlinear optics, the second-order Sum-Frequency Generation (SFG) process has a variety of applications for the in situ analysis of molecular/inorganic interfaces [1–10], often composed of The cascading of nonlinear crystals has been established as a simple method to greatly increase the conversion efficiency of single-pass second-harmonic generation compared to a single-crystal .
