How lasers work
How a CO2 laser works
In a CO2 laser, high voltage is applied to a mixture of CO2, N2, and He in the resonator generating the laser beam. The laser beam is then reflected and shaped by a series of mirrors that deliver the laser beam to the cutting head.
How a fiber laser works
In a fiber laser, a low-maintenance solid-state laser source generates a laser beam that is delivered through a fiber optic cable to the laser head. The glass fiber transfers the beam with a beam quality tailored for the cutting task at hand.
