Parents came home from the library with that one! It's ten years old and looks like it will be fun! Sorry to disappoint anyone but it seems like it's actually logical inside and you can learn from it.
When I get home I'll take look and confirm, but I believe it was laid out by type of expirament and then those are spread out in steps and how to do it. Including various sections based on Ruby and HeNe lasers among some of the other "older" lasers.
