Patent ID: 8081668

Claim:
A method for delivering laser pulses to a workpiece, comprising: triggering a laser to generate a set of first consecutive laser pulses each separated by a first time period and having a first energy level, the set of first consecutive laser pulses ending with a concluding laser pulse; triggering the laser to generate second and third laser pulses that are consecutive to the concluding laser pulse of the set of first consecutive pulses, the third laser pulse being separated from the concluding laser pulse of the set of first consecutive laser pulses by a second time period that is greater than the first time period, the second laser pulse being triggered at a predetermined time that causes the third laser pulse to have a second energy level that is substantially the same as the first energy level, the second laser pulse being separated from the concluding laser pulse by a third time period that is shorter than the first time period, and the third laser pulse being separated from the second laser pulse by a fourth time period that is intentionally shorter that the first time period; preventing the second laser pulse from reaching the workpiece; and allowing the set of first consecutive laser pulses and the third laser pulse to propagate to the workpiece.
