This physical process removes material. The material is completely removed from the top to the bottom surface, or part of the material is removed from the top of the material down from the specified depth. Material ablation is used for laser engravercutting, laser engraving and laser drilling.
There are also some new high-end laser marking machines, such as UV laser marking machine (laser wavelength: 355nm), green laser marking machine (laser wavelength: 532nm or 808nm). Their laser pointer effect is very fine and precise, but its cost is not as cheap as fiber laser marking machine and carbon dioxide laser marking machine.
According to the pumping method, solid-state ultraviolet lasers are divided into xenon lamp pumped ultraviolet lasers, k lamp pumped ultraviolet blue laser pointer and new laser diode pumped all-solid-state lasers. Generally, an integrated design is adopted, which has the characteristics of small spot, high repetition frequency, reliable performance, strong heat dissipation capacity, good beam quality and stable power.
This is the appearance of today’s laser engraving machine. It has been innovated to have wheels on the bottom so it can be moved. In addition, it has a polycarbonate window to help absorb all emitted radiation.
Teachers, trainers, and lecturers in teaching demonstrations and project demonstrations all encounter such embarrassment. They need to perform operation instructions on the computer side. The actions are limited and very convenient. How to let users completely liberate the demonstration in teaching, the real “where to go, where to go, where to go, where to point”. Allows users to maximize the advantages of body language in teaching and speech, making teaching and speech more vivid and perfect. The blue blue laser pointer pointer completely solves the inconvenience in the classroom and mouse use in the past, and will become an important technical problem. And market opportunities.
As you can see, surface roughness is permanently affected. Color changes appear as a result of different patterns on the surface. For high-quality markings, the black and white colors offer the best contrasts.
Of course, the process is optimized for each application and thus slightly different. If you have specific requirements, the best way to find out how the etching process works for your application is to ask a laser expert.If you want to further explore the physics behind laser technology, you can also watch free educational videos produced by the MIT.
