Manufacturing
The CO2 resonator is much larger and requires more energy, as electricity is introduced to a combination of gases to produce the laser beam. Mirrors help the light gain in intensity, preparing it to exit the resonator. After exiting the resonator, the beam must travel through a path comprising several cooled mirrors until it reaches the lens. This travel causes a loss of power and quality in the laser beam.
You can save time and reduce the number components. Tubular frames and metal structures are faster and more precise to assemble. You can complete your part in one programming step.
