Laser marking machines use laser beams to mark permanent surfaces of various materials. The effect of marking is to reveal the deep material through the evaporation of the surface material, or to “burn” the trace by the light energy to cause the chemical physical change of the surface material, or burn off some of the material through the light energy, showing the required etching.

Rapidly improve the depth of the laser marking process diagram
1. From the laser's power range, increasing the laser power will directly increase the depth of laser marking. However, it must be remembered that once the power of the laser is changed, the laser power supply, the laser chiller, the laser Q-switching system, and the laser mirror can be replaced and the cost will increase. The workload will also increase.
2. From the point of view of lasers, optimizing the beam quality of the laser will also increase the intensity and depth of the laser marking machine. This method is processed from the method of generating lasers, for example, in the laser cavity, such as changing the laser material, laser crystal or replacing higher-grade gas, replacing laser pump source with more reliable and stable quality, laser Measures such as full mirror and output mirror.
3, from the laser follow-up spot processing, the use of high-quality laser group can achieve twice the result with half the effort. For example, using a high-quality beam expander, the spot is expanded to a perfect spot similar to a Gaussian beam. The use of high-quality F-field mirrors allows the laser to pass through with better light focus and better spot. The energy used to make the spot in the effective web is more uniform.
4. If the above three basic methods cannot be changed, the laser marking machine can be used to achieve a better depth by replacing the field lens with a shorter focal length.
