I wish this book had been published when I first started as a grad student! Instead there was Loudon's "The Quantum Theory of Light" and Marlan Scully's "Quantum Optics" - both excellent books, but both lose sight of the fundamental physics, and do not really bridge the gap between most physics degrees and the subtle mathematical world of quantum optics. This is a book which really introduces the subject from a concise fundamental physics footing, taking into account that new grad students are not experts in the field - it is enough work for some students to come to terms with a lot of new mathematics, let alone try and understand where many physical approximations creep in - some quantum optics lectures simply introduce expressions without explanation, and this book seems to answer most of them.
A case in point is the quantum treatment of the Hanbury Brown-Twiss experiment, where in the treatement of one of the beamsplitter output ports, a subtraction appears. This book is the only place where I've clearly seen sufficient explanation, in a margin note, that this arises through conservation of energy (actually you are not handed this on a plate, but given a guided problem that shows how it arises, which is a good idea).
And here lies the only complaint about the book, that it uses margin notes. It might sound a strange complaint, perhaps its just me being stupid, but if you've spent a few years reading books and papers where you're used to scanning through single column blocks of text for a vital bit of information, your eyes don't immediately notice an off-set, small block of margin text (in small font, so it looks like a figure caption). A few times I've been caught out searching for explanations in the main body of the text, only to realise after much head scratching that its in the margin notes!
In all, I find this the best book I've ever read - it makes quantum optics enjoyable, simply because of the grass-roots physics. Not everybody in quantum optics is a theorist, some people actually have to do experiments, which is the hardest part of quantum optics.
Thankyou Mark Fox for making Quantum Optics accessible and enjoyable to all!
