This chapter discusses the most common nonlinear interactions, beginning with second-harmonic generation and proceeding to sum-frequency mixing and parametric phenomena. The approach is classical, using a nonlinear susceptibility. The techniques of birefringent phase matching and quasi-phase matching are described and analyzed. To facilitate the description of birefringent phase matching, a discussion of anisotropic crystals is provided. Second-harmonic generation using a focused beam is touched on, and the enhancement of nonlinear interactions in a resonant cavity is described. The use of periodically poled waveguides to provide efficient second-harmonic generation over a wide range of wavelengths is discussed.
Keywords: dielectric tensor, uniaxial, biaxial, second-harmonic generation, sum-frequency mixing, parametric amplification, parametric oscillator, birefringent phase matching, quasi-phase matching, periodically poled waveguide
