Fiber laser marking machin∑σ​e can also be called metal laser ✘₹•marking machine. Because it uses a fibφ♦er laser, it is a laser that uses ☆₩a rare earth-doped glass fiber✘&λ as the gain medium. Under the action ®εof the pump light, i↑₩∏↔t is easy to form a high power densit‍β↕y in the fiber, which caus​™es the laser energy levα♥×el of the laser workβ∞γ↔ing material "particle €δ↓↕number inversion" "When€ δε the positive feedback loo♣≠₽p (to form a resonant cavity)"₽ is properly added, the lasφ​ •er oscillation output can be form§♣'↓ed. The laser wavelength is 1064nm, wh♥•≥ich belongs to infrar••☆☆ed invisible light, and the ¥↑≈∞absorption rate of metal mate$↕rials for this wavelengt¶≈≈₽h is relatively high, so the f•• iber laser marking machine is mai₽φnly used for metal marking.

Many people will have a question: "Ca ✘ n all metals be marked with ₽≈✔≥a fiber laser marking m↕αachine?"-Yes, a fiber laser marking↔↕σ↕ machine can mark an≠↕&y metal material, but it is not soδ↑☆λmething The material can be pl∑✔ayed clearly, in othe&₹€'r words: not all metal materials can ac♥€♥hieve the desired effect.
