The UV marking machine adopts the international cutting-edge laser pumping technology, directly pumping semiconductor pump light (808nm) from the end face of the laser crystal, and outputting the laser through an optical mirror group. The light to light conversion efficiency of the laser is greatly improved, reaching over 45%, while the power consumption of the pump source is also reduced, resulting in a significant decrease in the power consumption of the chiller and the overall power consumption of the machine. End face pumping has better beam quality and higher peak power than side face pumping. Applied to marking medical devices, 3C industry, automotive industry, electronic components, electrical products, hardware tools, precision instruments, high and low voltage electrical appliances and other products.
