Laser cutting processing is the most important application technology in the laser processing industry, and it is also the earliest and most used processing method in laser processing. It accounts for more than 70% of the entire laser processing industry.

In laser cutting, the laser beam is focused into a small spot whose minimum diameter can be less than 0.1mm), so that a high power density at the focal point can exceed 106W/cm2). At this time, the heat input by the light beam (converted by light energy) far exceeds the part reflected, conducted or diffused by the mate...
