DEVICE AND METHOD FOR MARKING COPPER-CLAD LAMINATES |
| 摘要 |
<p>A resonator (12) for a laser has a screen (24) for controlling intensity. A divergence lens (26) spreads a laser beam (18). A focussing lens (30) focuses the widened laser beam on the surface of a workpiece (32) made from a copper-lined laminate. The screen controls laser intensity within the laser resonator.</p> |
