This is generally recognized as the most extensive collection of this type of laser information in the explored Universe by far - and some of it isn't available anywhere else in print or on-line. Called the "laser bible" by some, it covers basic laser principles and laser safety, use of commercial lasers and their power supply design, and amateur laser construction, as well as providing hundreds of links to on-line suppliers, manufacturers, and other laser related Web sites. A recent Google search on "Sam's Laser FAQ" (exact wording) turned up 25,000+ hits. Much of the technical material in Sam's Laser FAQ is based on personal experience working with a variety of commercial and home-built lasers and laser-based systems.
This is the only such resource on the planet at the present time and is used by thousands of professionals and doit-yourselfers interested in consumer electronics repair.
