Abstract:
1. A method to produce plasma by photon radiation from a target body comprising target material having an ablation threshold and an absorbance of said photon radiation, comprising: selecting an ablation area on the target body for the generation of plasma from a spot on said ablation area, selecting a radiation geometry for said photon radiation, to focus said photon radiation onto the spot on said target body, controlling ablation of said target body by: directing said photon radiation along a radiation path from a radiation source to said spot on the target body via a turbine scanner, in which reflective surfaces are faces of a polygon that is arranged to rotate around a rotation axis, and generating said plasma by scanning said photon radiation so that said spot moves along an ablation path on said ablation area.
