非线性光学（第3版）

Nonlinear Optics (3rd Edition) is an impressive and informative book on the subject of nonlinear optics. The latest edition offers a comprehensive overview of the topic, with chapters that cover everything from the formal definition of the nonlinear susceptibility to the molecular origin of the nonlinear optical response. The book is engagingly written and informative, making it a valuable resource for physics and optics students and researchers. In the first few chapters, the author provides a clear description of nonlinear optical processes and the formal definition of the nonlinear susceptibility. Wave-equation descriptions of nonlinear optical interactions and the quantum-mechanical theory are also explored, providing readers with a solid foundation for further study. The molecular origin of the nonlinear optical response is another fascinating area covered in this book. The author discusses non-linear susceptibilities calculated using time-independent perturbation theory, semi-empirical models of the nonlinear optical susceptibility, and the nonlinear optical properties of chiral media. Other topics covered in the book include processes resulting from the intensity-dependent refractive index, stimulated scattering processes, and optically-induced damage and multiphoton absorption. Ultrafast and intense-field nonlinear optics are also explored. Overall, Nonlinear Optics (3rd Edition) is an excellent book that provides a comprehensive overview of the subject. It is well-written, informative, and engaging, and I would highly recommend it to anyone interested in the field of nonlinear optics.
