While the latter relies on a diode with a light power of less than 10 watts, the CO2 laser is capable of reaching a power of several hundred watts making it possible to cut multiple materials. To do this, the cutter sends an electric current through a glass tube containing a mixture of gases, which creates a photon emission, or in other words, light. At one end of the tube, there is a reflecting mirror and at the ot... more
