CO2 laser
thingiverse
You'll require two glass tubes: one 200mm long with a 20mm diameter (keep in mind, it's a beta-version), and another 200mm long tube with a 6mm outer diameter. A high voltage transformer is also necessary, as well as a vacuum air pump, water pump, and plenty of water to sustain operations for an extended period. Additionally, a reliable sealant will be needed for secure connections. The most expensive components are the molybdenum mirror and salt window for output. This project is strictly intended for entertainment purposes only! Be extremely cautious when handling equipment. As the creator, I may make mistakes since I'm just 13 years old. I've updated laser couplings with new features: o-ring holders for improved contact and pre-drilled holes for M3 screws on top of the largest components.
