Abstract
Official abstract text for this publication.
The invention relates to a method for laser boring or laser cutting a workpiece ( 2 ), wherein—electromagnetic radiation ( 10 ) emitted from a laser strikes the workpiece ( 2 ) and—a liquid ( 16 ) which contains nanoparticles ( 18 ) is located on a workpiece ( 2 ) face facing away from the laser such that—the electromagnetic radiation ( 10 ) emitted by the laser strikes the nanoparticles ( 18 ) when the electromagnetic radiation ( 10 ) has passed through the workpiece ( 2 ). The nanoparticles are designed such that the majority of the electromagnetic radiation ( 10 ) is absorbed by the nanoparticles ( 18 ) in that the electromagnetic radiation ( 10 ) generates collective excitations, in particular plasmons such as surface plasmons for example, in the nanoparticles ( 18 ).
First claim
Opening claim text (preview).
1 . A method for laser drilling or laser cutting a workpiece, wherein electromagnetic radiation emitted by a laser impinges on the workpiece and a liquid containing nanoparticles is situated on a side of the workpiece facing away from the laser such that electromagnetic radiation emitted by the laser impinges on the nanoparticles once the electromagnetic radiation has passed through the workpiece, wherein the nanoparticles are embodied in such a way that a predominant portion of t…
