Easy Explanation of Basic Quantum Optics: Book Recommendations

[Alice Jin]

I'm looking for Basic Quantum Optics explaining very easily the concept and fundamental principle. What are you going to recommend? Thanks in advance.

Gerry&Knight's "Introductory Quantum Optics" is pretty good.

Although quantum optics is never "very easy", you do need to know at least the basics of quantum mechanics (e.g. the first few chapters in Sakurai) in order to understand any book on quantum optics.
