Chapter Two Working principle and structure
2.1. Marking principle
*Through the laser light energy evaporat the material in the surface and show deep
material;
*Through the laser light energy cause the surface substance chemical physical change and
"engrave" the needed text pattern;
*Through the laser light energy burned part of the material, then show the design, text of
etching.
