<p>A method for producing a precision-machined workpiece using pulsed laser assembly, wherein a laser pulse is produced with the pulsed laser assembly and subsequently directed through the workpiece. The laser pulse includes a first relatively low energy portion and at least two relatively high-energy micro-pulses subsequent to the first relatively low energy portion. The pulsed laser assembly includes a pulse generator, a lasing pump operationally connected to the pulse generator, and at least one switch operationally connected to the pulse generator and the lasing pump. The switch is synchronized with the pump pulse and actuates the separation of the laser pulse into a plurality of discrete micro-pulses.</p> |
