One of the most versatile tools in a shop or makerspace is a laser cutter. The recently funded Glowforge makes having one in your garage a possibility.

With so much exciting around laser cutters, you might be wonder what is a laser anyway? There are two primary laser types: Gas and Diode.  Jordan Bunker goes into detail in the Make: Skill Builder article, about the difference.

The pictures and diagrams alone are worth the look. The diagram on how a laser diode emits light is one of my favorites. (Actually, I think it is a good general purpose “led/diode diagram.”
