The CO2 Resonator is more powerful and uses more energy. This is because electricity is used to mix gases to make the laser beam. Mirrors assist the light in increasing its intensity, which prepares it to exit the resonance. Once the beam has left the resonator it must travel through several cooled reflections before reaching the lens. This is what causes the laser beam to lose its power and quality.
Laser systems are available for electronics manufacturing. They can perform cutting, welding marking, marking, and ablation with high precision.
