This is the content for Hive76's introduction class to laser cutting.
In this class we will cover the following:
Our laser cutter uses a 45W CO2 glass laser tube. The laser works by exciting CO2 atoms that release infrared light a.k.a. heat. These Infrared photons bounce back and forth inside the laser tube between two mirrors. Once they get to a specific power level, they exit through one mirror, travel through a series of mirrors, and are focused to a point.
