In recognition of Father's Day, I thought I'd give a shoutout to possibly the Father of DIY Laser Building, C. Harry Knowles of Metrologic. Check out his biography "Genius in America" by Mary Ellen Hendrix for more info. His article in the December 1969 Popular Electronics (seen below with one of his early tubes) really started the hobby. A great example is seen below featuring a start button, excellent craftsmanship, and purple paint that screams the early '70s. And from a technical conference from around the same time, a pointer built by John Hall.:)

The introduction of laser disk players and supermarket scanners in the late '70s incorporating He-Ne lasers really stimulated DIY laser building. Here's a very well built laser made in 1985 by Mr. Tony Gongora with a tube harvested from such a player. I got it along with his notes on the project.
