This book is to the field of quantum electronics as Jackson's thick maroon book is to classical electrodynamics. The book covers a wide range of topics from basic concepts to advanced methods to real systems. It is a valuable reference, providing a wealth of knowledge for those who can get through it. Unfortunately, the text is brief and the derivations tend to make leaps and bounds without explanation. This is generally bad news for the student who wishes to learn the material for the first time. The use of examples throughout the book is appreciated, though they often deal with very specific problems and do not lend very well to understanding the basic concepts. Some prior knowledge of the subject, either mathematical or intuitive is recommended before delving into "Quantum Electronics". Kinda like Jackson's book, eh? My greatest complaint is the significant overlap with Yariv's other classic, "Optical Electronics". Imagine my shock and outrage when I discovered that the book I had just purchased repeats large sections of a book I already have, page-for-page verbatim. Perhaps a suggestion for future editions would be to combine the two books into one two volume work, thus eliminating redunancy and freeing up space to cover the material in greater detail.
