Abstract
An fast steering mirror ( ), such as a PMN actuated mirror, is positioned in a beam path ( ) of a stage-based positioning system ( ) to continuously move a laser beam ( ) in a high speed prescribed pattern about a nominal target position ( ) to spatially separate focused laser spots ( ) generated at a high laser repetition rate and thereby create geometric features having dimensions greater than those of the focused laser spot ( ). A series of laser spots ( ) at a given repetition rate appear as a series of larger diameter laser spots at a lower pulse rate without beam quality problems associated with working out of focus.
