In this second edition, there is an enlarged chapter on decoherence, as well as additional material dealing with elements of quantum computation, entanglement of pure and mixed states as well as a chapter on quantum copying and processors. These topics are presented in a unified and didactic manner. The presentation of the book is clear and pedagogical.
"The third edition of this book contains extensive and thorough coverage of basic laser-related phenomena including quantization of the electromagnetic field, quantum theory of coherence, laser theory using both the master equation and the Langevin theory, and generation of non-classical vibrational states of ions in a Paul trap. ... it will be of interest to a great variety of readers, including graduate students, scientists and engineers. ... It is a valuable addition to textbook literature in quantum optics." (Christian Brosseau, Optics & Photonics News, osa-opn-org, March, 2017)
