Parameter setting of fiber laser marking field mirror

Friends who have used laser marking machines know that the marking depth of laser marking machines can be freely adjusted, but there are still many people who do not know this when they first come into contact with laser marking machines. I even found that they ask Du Niang: How to adjust the marking depth of laser marking machines? Today, I will talk to you about how to adjust the marking depth of the laser marking machine.

1、 Increasing the power of the laser can directly increase the depth of laser marking, but the prerequisite for increasing the power is to ensure that the laser power supply, laser water cooler, laser lens, etc. are matched with it. The performance of its related accessories should be able to withstand the efficiency after power increase, so sometimes it is necessary to temporarily replace matching parts. But the cost will increase, and the workload or technical requirements will also increase.

2、 In order to optimize the quality of the laser beam, it is necessary to replace stable laser pump sources, laser mirrors, and output mirrors, especially their internal laser materials, crystals, etc., which is beneficial for improving the quality of the laser beam and enhancing the intensity and depth of the marking.

3、 From the perspective of laser spot processing, using high-quality laser groups can achieve twice the result with half the effort. For example, using a high-quality beam expander, the light spot can obtain a perfect spot similar to a Gaussian beam after its beam expansion. By using high-quality F-field lenses, the laser passing through has better focusing intensity and spot size. The energy of the light spot is more uniform in an effective format.

4： If the above methods are not enough, we can try using better and shorter focal lengths to increase the energy of the field lens. This is very important.

From the above analysis, can you know how to adjust the marking depth of the laser marking machine? Of course, when we purchase a fiber laser marking machine, we first need to understand what type of workpiece our product is, what characteristics and requirements it has, and have a better long-term plan. For example, the depth of the workpieces produced now is relatively shallow, but the traces produced in the future will be very deep, so we should purchase with the deepest configuration. We can use existing equipment to set relevant parameters, but we can only make simple markings when starting to purchase configurations, and then we can only change the hardware.
