I'm looking for a textbook on laser physics. I'm considering either Lasers by Siegman or same title by Eberly & Milonni. I want a textbook more directed to a physicist and not the more engineering style, which may lack rigour (from the physics point of view). I'm not very comfortable with books that talk their way to certain results rather than showing it mathematically from fundamental equation. Can anyone recommend one of the books over the other, or maybe a completely different textbook?
