Abstract

A method for laser shock peening of a component, in particular at points that are difficult to access, includes the steps of: supplying a first end of a flexible optical waveguide, which end is designed in the form of an optical waveguide brush having a plurality of divergent optical waveguide fibres, to a point of the component to be treated by laser shock peening; generating laser shock pulses, which are coupled in at a second end of the optical waveguide, by a laser beam source; and discharging the laser shock pulses by the optical waveguide brush into a process zone at the point of the component to be treated. A use of an optical waveguide brush, a system for laser shock peening of a component, and a mobile laser shock treatment station are also described.
