The laser beam is emitted by using an oscillator and scanned the usage of a replicate (known as a scanning mirror), and a focusing lens is then used to focal point the beam on the goal and mark it by means of altering the surface. Because laser marking entails the usage of mild to exchange the goal surface, this technique is greater resistant to abrasion than ink-based marking, and the marking does now not fade over time.
