With the wide application of fiber lasers in laser devices, the laser marking machine is also booming.However, the marking patterns we see in daily marking products are basically black and white gray.From the current laser marking process, only some fiber lasers can be color-coded on stainless steel. When marking the stainless steel material, the laser changes the color of the surface layer of the material by adjusting the laser beam so as to obtain different color decorative effects.The advantage is that the pulse width and frequency are independently adjustable. Adjusting one of them does not affect other laser parameters. This is not what the Q-switched structure laser does.This feature increases the infinity of stainless steel color marking.Pulse width, power, filling method, delay parameters and other factors will affect the color effect in the actual marking operation.

Laser marking machine working principle 1. The working principle The laser is gathered at the very high energy density on the surface of material. In a very short of time, the surface of the material gasification, and by controlling the effective displacement of the laser beam, accurately burned exquisite patterns or text. The laser mark is clear and permanent, can not be rubbed and changed. While the laser marking of the non-erasable coating to also have a certain anti-counterfeiting effect. Laser source   2. Eight advantages. a. Marking effect is permanent Marking will not fade due to environmental relationships (such as touch, acid and degrading gas, high temperature, low temperature, etc.). b. Marking effect has security The marking is not easy to imitate and change, has a strong security.
