A laser is a type of light that, like other natural light, is produced by the transition of atoms (molecules or ions, etc.).

However, it differs from ordinary light in that the laser only depends on spontaneous radiation for a very short period of time, and then the process is completely determined by excitation radiation. Therefore, the laser has very pure color, almost no direction of divergence, very high luminous intensity and high coherence.

Laser cutting is achieved by using the high power density energy generated after laser focusing. And controlled by computer, through the pulse laser discharge, thus the output controlled repeated high frequency pulse laser, the formation of a certain frequency, pulse width of the beam, the pulse laser beam through the light path transmission and reflection and through the focusing lens group focused on the machining surface, forming a subtle, high energy density, intensity, focal spot near to processing surface, To melt or vaporize the processed material at an instantaneous high temperature.

Every high energy laser pulse instantly sputtered out a small hole on the surface of the object, under the control of the computer, laser processing head and be processed material according to the pre-drawn graphics continuous relative movement dot, so that the object will be processed into the desired shape.

The process parameters (cutting speed, laser power, gas pressure, etc.) and the movement trajectory are controlled by the NUMERICAL control system, and the slag at the slit is blown off by the auxiliary gas of a certain pressure.
