The principle of laser marking machine is the use of laser beam marking on the surface of a variety of different substances permanent marking, the use of surface evaporation of substances to reveal the deep material, marking the exquisite patterns, text, trademarks, etc., has been widely Used in electronic components, precision instruments, aerospace, shipbuilding, mobile phones, and many other areas. In the laser marking machine structure, we all know that the laser is its core components, how to choose a suitable laser marking machine laser is particularly important, especially in some special industry applications, the more stringent requirements of the laser, then In the choice of the laser above, we should pay attention to what matters?
First, the laser profile
With more and more types of lasers, lasers in accordance with the work of people will be divided into Q-switched lasers, ultrashort pulse lasers, pulse lasers and continuous lasers several types. In accordance with the working medium will be divided into solid-state laser lasers, gas lasers, semiconductor lasers and chemical lasers four categories. The wavelength of the laser from the far-ultraviolet region of the shortest wavelength of 210 to the microwave wavelength of 0.7mm of the longest wavelength, the laser band has reached thousands, used in different types of laser equipment needs.
The development of lasers has been more than 50 years of history, from the first 1960 T.H.Mehmann manufactured the world's first ruby ​​laser to the present stage of the X-ray laser and free electron lasers. The development of lasers can be described as ever-changing.
Second, laser marking machine laser options
The face of such a wide variety of lasers, laser marking machine equipment, the choice is the key, first of all is to meet their own needs to meet the continuous work and harsh environmental factors, the second point is to meet the processing accuracy, Three points is the laser marking machine in the process of stability and stability of the laser power output.
