Method and device for structuring at least one region of a solid surface uses a nano- to femto-second pulsed laser to form a grid structure with a polarized beam and relative movement to the surface

摘要

A method of structuring at least one region of a solid surface (9) comprises using a nano- to femto-second pulsed laser (1) to produced a nanometer grid structure (LIPPS) by means of a polarized (4) laser beam with a relative movement between the plane of polarization and the object surface to produce the grid. Independent claims are also included for the following: (A) A unit with a laser as above; (B) A further unit for the above; and A method of laser modification of solid surfaces.
