Most of patterns marked by laser marking patterns are black and white. You can choose mopa laser marking machine in order to get color ones.
The advantage of mopa fiber laser is that its pulse width and frequency are independently adjustable. Adjust one of the parameters will not affect the other, which is different from Q-switched laser.
When marking the stainless steel, the laser can change the color of the surface layer of the material by adjusting the laser beam to obtain different effects. The pulse width, frequency, power, speed, fill mode, delay parameters and other factors will affect the color effect.
