Nonlinear optics
TL;DR: In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.

Quasi-phase-matched second harmonic generation: tuning and tolerances
TL;DR: The theory of quasi-phase-matched second-harmonic generation in both the space domain and the wave vector mismatch domain is presented in this paper, where various types of errors in the periodicity of these structures are analyzed to find their effects on the conversion efficiency and on the shape of the tuning curve.
