Lasers can deliver high power to very small areas. This property is used in laser marking of plastic parts. Of the many types of lasers, a 1064nm Nd:YAG laser with a beam-steering system is the usual choice for plastic marking systems. It is also possible to use a 10640nm CO2 laser through a mask. The energy is used to modify the appearance of a plastic part, in particular to create a colour contrast with the background colour of the part.
