1. Basic principles of laser cutting

Laser cutting is a process of cutting by focusing a high-energy laser beam on the surface of a material, using the heat energy of the laser to quickly melt, vaporize or ablate the material. The beam generated by the laser is focused to a very small point through an optical system, forming a high-temperature energy-intensive area with a temperature of several thousand degrees Celsius. This process is usually accompanied by the use of jet-assisted gases (such as oxygen, nitrogen, etc.) to help remove the molten metal produced during the cutting process and improve the cutting quality and speed.
