How to improve the marking depth of laser marking machine
Jun 25,2021
Many users of laser marking machine hope to increase the depth of the marking machine. So, how can a ready-made laser marking machine increase the depth of marking?
1. In the power range of the laser, increasing the laser power directly increases the depth of the laser marking, but you need to remember that once you change the laser power, you can replace the matched laser power supply, laser water cooler, laser Q-switching system, and laser reflection Mirror, etc., the cost will be greatly increased, and the workload will also increase.
2. Optimizing the quality of the laser beam can also increase the intensity and depth of the laser marking machine. This method is processed by manufacturing lasers, such as replacing good laser materials, laser crystals or replacing higher-level gases, replacing more reliable and stable laser pump sources, laser mirrors and output mirrors and other laser cavities.
3. From the point of view of laser spot processing, the use of high-quality laser sets can achieve results with half the effort. For example, use a high-quality beam expander to obtain a spot similar to a Gaussian beam after it is expanded. Using high-quality F-field mirrors, the passing laser has better light focusing intensity and better spot. The energy of the light spot is used more uniformly in an effective form.
4. If the above three basic methods cannot be changed, the field lens can be replaced with a shorter focal length, so that the laser marking machine can type in a deeper range.
