Abstract
A laser processing system provides a burst of ultrafast laser pulses having a selectively shaped burst envelope. A burst pulse laser includes a high repetition rate ultrafast laser to deliver a pulse train with each pulse in the train having an independently controlled amplitude. The respective amplitudes of each ultrafast pulse in a group define a 'burst envelope.' In addition to independently controlling the amplitude of each ultrafast pulse within the burst envelope, the system may also provide selective control of spacing between each ultrafast pulse and/or the overall temporal width of the burst envelope. Thus, the system provides selective shaping of the burst envelope for particular laser processing applications.
