With the rapid development of laser technology, laser technology is also gradually close to our daily life, bringing a lot of convenience to our current life, giving us better products and services. 
As an important field of laser technology application, laser marking has been widely used in many fields, which has benefited all aspects of our production and life. 
After decades of development, laser marking machine, as a modern precision machining method, has unparalleled advantages compared with traditional machining methods such as printing, mechanical marking, EDM and so on. Fiber laser marking machine china has the advantages of maintenance-free, adjustment-free and high reliability, and is especially suitable for areas with high precision, depth and smoothness, so it is widely used in luxury goods industry. 
Machinable metal products are iron, copper, stainless steel, gold, alloys, aluminum, silver and all metal oxides.

Yu label marking machine has been based on the needs of users, relying on strong technical force, in line with the principle of providing users with the most advanced and suitable products for R & D, tailor-made the best products for users. 
Key benefits: 
The advantages of miniaturization and intensification brought about by the low manufacturing cost of glass fiber, the maturity of technology and the tolerance of optical fiber. 
The glass fiber does not need to match the incident pump light as strictly as the crystal, which is due to the wide absorption band caused by the non-uniform broadening caused by the Stark division of the glass matrix. 
The glass material has very low volume-area ratio, fast heat dissipation and low loss, so the upconversion efficiency is high and the laser threshold is low. 
There are many output laser wavelengths: this is because the energy levels of rare earth ions are very rich and there are many kinds of rare earth ions. 
Tunability: due to the wide energy level of rare earth ions and the wide fluorescence spectrum of glass fiber.
