Abstract

In this paper, the Nd:YAG laser engraving system is studied for the purpose of engraving image, figure, and characters on the surface of metal, ceramic, plastic, leather, etc. First of all, the high repetition and high power Nd:YAG laser is set up; secondly, the 2-mirror 2-axis optic scan system is analyzed and designed; third, the software is developed to control the laser beam in vector mode or in dot matrix mode. The expanded laser beam is directed toward the worksurface through a f-(theta) lens by computer controlled X and Y axis mirror, and moves in a fixed path, a mark is engraved or marked. As a result, the marking field of 100 X 100mm and spot size of 0.088mm are obtained.
