Fundamentals of Nonlinear Optics

A stepwise introduction, this book begins with the wave equation in its simplest form. The author carries readers gently to deeper comprehension by progressively removing simplifying assumptions. He guides readers to a clear understanding of core aspects of three wave interactions, including second harmonic generation, sum and difference frequency generation, and the electro-optic effect. The concepts of phase matching, bandwidths, gain, and so on unfold naturally from these formalisms and extend well to higher order processes such as four-wave mixing, Raman, Brillouin, and two-photon processes. The author highlights recent developments and key applications throughout the text.
