The influence of the interaction between laser engraver and material largely depends on the wavelength and power level of the laser, as well as the absorption characteristics and chemical composition of the material.
The first generation of laser marking machine is the lamp pump YAG laser marking machine. It is large and has low energy transfer efficiency. But this opened up the laser marking industry.The second generation is a diode-pumped laser marking machine, which can be divided into two development stages: a diode-pumped solid-state YAG laser marking machine, and then a diode-pumped solid-state YAG laser marking machine. The fiber laser marking machine has high energy efficiency and can generate 10 watts to 2,000 watts according to the needs of laser marking, laser engraving and laser pointer.
Fiber laser marking machine has become the mainstream of metal material laser marking machine. The laser marking of non-metallic materials (laser wavelength is 10060nm) is mainly a CO2 laser marking machine, and there is no major change in history.
blue laser pointer have positive and negative effects on society. Some of its positive effects on society are that it may lead to the production of new military weapons. By trying to complete the task manually, it also helps to cut the material accurately, rather than causing errors. It may have some negative effects on society, that is, the amount of radiation emitted is too strong to be exposed, and if it occurs, it may eventually cause some major problems/side effects.
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 the material melts and cools down within milliseconds, localized changes occur on the surface. Surface roughness changes, creating permanent markings.What do changes in roughness look like? Let’s look at magnified images taken using an electron microscope.
