Abstract
A device for marking copper-clad laminates comprises a laser ( ), in whose resonator ( ) there is an intensity-controlling screen ( ), an expanding lens ( ) for expanding the laser beam ( ) and a focusing lens ( ) for focusing the expanded laser beam ( ) on the surface of a workpiece ( ) in the form of a copper-clad laminate. In the corresponding method for marking copper-clad laminates a laser beam ( ) is expanded, and the expanded laser beam ( ) is focused on the surface of a workpiece ( ) in the form of a copper-clad laminate, with the laser intensity inside laser resonator ( ) being controlled by a screen ( ).
