Solid-State Laser Engineering is written from an industrial perspective and discusses in detail the characteristics, design, construction and practical problems of solid-state lasers. Emphasis is placed on engineering and practical considerations, with a phenomenological treatment using models being preferred to abstract mathematical derivations. This new edition has been updated and revised to include important developments, concepts and technologies that have emerged since the publication of the first edition.
I'm four editions behind, mine is the second edition, it's excellent for laser basics. With cheap commercial lasers elements widely available, I suspect that most people working in this broad field will never have to do much design work. You may want to look at it before buying, get thee to a really good library or technical bookstore.
