Fiber laser engraving machine can realize the coloring of goods, but it does not mean that all fiber laser engraving machines can realize coloring engraving, which is second only to fiber laser engraving machine, that is, fiber laser using MOPA pulse technology can meet the coloring demand. Generally, products made of stainless steel, titanium, chromium, aluminum and other metals mainly meet the needs of coloring. Fiber coloring mainly changes the surface layer of processed materials by adjusting the laser beam to change the color, so as to obtain ornaments of different colors. influence. So far, the problem that customers want to use laser marking equipment to realize product coloring has been well solved.

The advantage of MOPA laser is that its pulse width and frequency can be adjusted independently. Adjusting one of them will not affect other laser parameters, which is not available for Q-switched lasers. The characteristics of MOPA structure bring infinite possibilities for stainless steel color labels. In the actual marking operation, pulse width, frequency, power, speed, filling mode, filling spacing, delay parameters and other factors will affect the color effect. The influence of these parameters will make the characteristics of color change not unique, but interrelated and interactive.

The basic principle of stainless steel color marking is to use the laser heat source with high energy density to act on the surface of stainless steel materials to produce colored oxides, or generate colorless and transparent oxide films. The reason for this is the light interference effect of the films. Colorful effect. By controlling laser energy and parameters, oxide layers with different thicknesses and colors can be realized, and even color gradient marking can be realized.

Laser engraving machine may not be able to carry out color marking. Color classification must be based on material. Some materials can only be marked with black and white. Therefore, onsumers can try the marking effect of the device in advance before making a decision.
