Patent ID: 8498037

Claim:
A method for processing workpieces, the method comprising: performing a laser processing operation in which a laser beam is directed at a first mirror face and at a second mirror face of a redirecting mirror, the second mirror face being completely surrounded by the first mirror face, providing, at the first mirror face which is supported in a stationary manner, a constant redirection of a first partial beam having a first fraction of a laser power of the laser beam impinging on the redirecting mirror, wherein, during the laser processing operation, a drive device produces, from a starting position in which the second mirror face lies in a same plane as the first mirror face, a pendulum movement of the second mirror face at a pendulum frequency of more than 2000 Hz relative to the first mirror face for redirecting a second partial beam having a second fraction of the laser power of the laser beam impinging on the redirecting mirror to produce a pendulum movement of the second partial beam relative to the first partial beam.
