This book is actually an update to The Laser Cookbook, also written by G. McComb, and which is apparently still in print. That book has gotten very high marks here on Amazon; Lasers, Ray Guns, and Light Cannons contains everything in Laser Cookbook, plus new information on laser diodes, and several additional projects.
Apparently, some folks get upset when a book, like this one, tries to be camp with a playful title and comic-book art. It's what's inside that matters, and there is lots of good information here, from a writer who clearly knows how to explain technical details. For my money, this book is a terrific introduction to the world of hobby lasers.
