While visiting Making it Happen, we spent most of our time with the big CNC laser they have. In this video, I will try to explain at a high level how a CO2 laser works and show the part of the real laser.
The basics of how a CO2 laser work is similar to a florescent light. High voltage is used to excite the gas within a glass tube. When excited, the gas releases photos that we see as visible light. These lights give off incoherent light. That means the photos are of different phases and frequencies.
When CO2 is excited with high voltage, the photos released are of the same phase and frequency. This creates what is called coherent light. Within the laser resonator, the light bounces back and forth between two mirrors until there is enough light to start exiting through the one mirror that is not fully reflective.
As the light that exits is our laser light. the photos are all traveling in the same basic direction. After bouncing off a few mirrors, they are run through a lens that focuses the light onto the cutting surface.
At one point in the video, I asked Leon what his daily carry knife was. If you have a daily carry knife, what is it? I have a Gerber US1 that I really like and have mentioned on the channel before.
