Abstract:
1. A laser processing machine comprising: a beam splitter for splitting an incoming laser beam into a first laser beam having a first intensity and a second laser beam having a second intensity; a first focusing mirror for focusing the first laser beam onto a first laser processing site on a workpiece at an angle from a direction directly above the workpiece; a second focusing mirror for focusing the second laser beam onto second laser processing site on the workpiece at an angle from a direction directly above the workpiece; one or more actuating drives to which one or more of the beam splitter, the first focusing mirror, and the second focusing mirror are mounted; and a movable optical sensor adapted and arranged for monitoring laser processing of the workpiece, wherein the movable optical sensor is disposed above the first or second laser processing site and between the first and second laser beams.
