The Basics of CO2 Laser Technology
CO2 lasers utilize carbon dioxide gas, which is electrically stimulated to produce laser beams. This gas mixture typically includes helium and nitrogen. When electricity excites the molecules, they emit light particles that concentrate into a beam.
Components of a CO2 Laser Cutting Machine
- Laser Resonator: This part contains the CO2 gas mixture and is where the laser beam is generated.
- Beam Path: Once generated, mirrors direct the beam towards the cutting head.
- Cutting Head: Here, the beam is focused through a lens to achieve high precision.
- Control System: Advanced software directs the machine’s movements, ensuring precision cuts.
How It Works in Practice
The process begins with loading a design into the control system. The machine’s software guides the laser head along the material surface. As the laser beam strikes the material, it absorbs the energy and heats up quickly, vaporizing at the point of contact. This method is excellent for cutting organic materials due to its wavelength compatibility1.
