The laser marking has been widely used because of clarity
and long life of the laser marked patterns. The marking
quality depends on the optical parameters of the system.
This paper discusses the relationship among the system
parameters, such as energy density, image position, mask
position, etc. The experimental results of the energy
density thresholds of some materials are listed. Those
results are useful for designing the optical system of a
laser marking system.
