Advantages of 355nm UV laser marking machine Ultraviolet laser marking machine has the characteristics of short wavelength and small spot. It adopts 355nm laser, which is the first choice for high precision laser engraving machine and marking machine. Ultraviolet laser marking machines are known as “photo-etching” effects. High-energy ultraviolet photons directly destroy the chemical bonds of materials by “cold treatment”, and the processed parts have smooth edges and minimal carbonization. In addition, UV laser energy can be effectively absorbed by most materials and has good focusing performance, so it can be finely micromachined in a small space area, which has very high research value and broad application prospects. In layman’s terms, all lasers are excited by their working medium and excited to an excited state. Some photons (atoms) are on a low-energy step called metastable state. The higher the absorption energy, the higher the energy level step, and the const...
