METHOD AND LASER ASSEMBLY FOR PROCESSING A WORK PIECE USING A PULSED LASER BEAM |
| 摘要 |
A method and a laser assembly process a work piece using a pulsed laser beam. In the method, during processing the lateral distribution of the spectral phase is varied non-linearly over the duration of a laser pulse and/or at least between two laser pulses that at least partially overlap on the work piece. |

1. A method for processing a work piece, which comprises the steps of:
providing a pulsed laser beam, in the pulsed laser beam a lateral distribution of a spectral phase within a time duration is varied nonlinearly during a processing over a beam cross section of a laser pulse and/or at least between two laser pulses that overlap at least partially on the work piece. |
