"an excellent book, very well organized and written. It includes a good number of problems at the end of each chapter…. I recommend this book to anyone teaching Nonlinear Optics." —Dr. Baldemar Ibarra-Escamilla, Instituto Nacional de Astrofísica, Óptica y Electrónica, México"Professor Joe Haus has done a magnificent academic job of completing the second edition of this already excellent introduction…. Even in the absence of Prof Peter Powers, the main basic concepts were kept and touched up, and the revised chapters and new chapter, which brings to the nonlinear optics community and newcomers the expanding area of quantum nonlinear optics, updates the book. Great work!" —Anderson S. L. Gomes, Universidade Federal de Pernambuco (UFPE), Brazil."This is definitely an excellent book that I will push all my students to read." —Prof. Lei Zhou, Fudan University, Shanghai, China"a pragmatic approach to learning the essential concepts needed for all practitioners in the field… with many realistic problems using material data and numerical algorithms to explore nonlinear phenomena. This book is destined to be very popular among students as well as with researchers in this field." —Paras N. Prasad, SUNY Distinguished Professor of Chemistry, Physics, Electrical Engineering and Medicine, State University of New York at Buffalo"This book contains fruitful discussions covering both theoretical and practical topics. It will be a very valuable reference for scientists and engineers in the optics and photonics community."—Qihuang Gong, Cheungkong Professor of Physics and Boya Chair Professor, Peking University"notable for its clarity, dedication to the SI system, and the fact of covering several sub-areas without falling into the trap of becoming too specialized in any one of them. It’s one of the books that I always suggest to my students. The new quantum NLO section at the end should be a valuable addition." —I
