On large area LIPSS coverage by multiple pulses
The phenomenon of covering large areas with coherent LIPSS produced by multiple, adjacent spots is investigated by varying spot overlap and irradiation dose per spot. In contrast to the typical experimental arrangement, the linear traces of spots were produced by discontinuously advancing the sample between the individual spots. We show that even with almost no overlap the LIPSS patterns appear to be coherently connected. (C) 2014 Elsevier B.V. All rights reserved.
