Laser vaporization cutting
The high-energy-density laser beam is used to heat the workpiece, so that the temperature rises rapidly, reaching the boiling point of the material in a very short time, and the material starts to vaporize and form vapor. The jetting speed of these vapors is very high, and at the same time as the vapor jets, cuts are formed in the material. The heat of vaporization of materials is generally very large, so a large power and power density are required for laser vaporization and cutting.
