Choice Review
Band (Ben-Gurion Univ., Israel) offers a thorough explanation of the interaction of light with matter. The book encompasses concepts from several cross-disciplinary fields, including electromagnetism, optics, spectroscopy, quantum optics, and lasers. The discussions cover both linear and nonlinear types of interaction phenomena. A brief explanation of the propagation of light in optical fibers is presented in the last chapter. The Gaussian units system is used generally in the book, and the International System of units (MKS) is introduced selectively in some cases. The book is well illustrated, and a few figures are reproduced in color. Problems are interspersed within the chapters. A list of references and five relevant appendixes are included. Readers are assumed to have a background in electricity and magnetism. ^BSumming Up: Recommended. Upper-division undergraduates through faculty. O. Eknoyan Texas A&M University
