A workpiece (1), in particular a plate-shaped workpiece, made of a material (2) which at a material thickness corresponding to the workpiece thickness (D) transmits more than approximately 10%, preferably more than approximately 20%, and especially preferably more than approximately 50% of near infrared laser radiation (4), has according to the invention scattering centers (3) arranged distributed in the material (2) for scatting the near infrared laser radiation (4) in such a way that, through multiple scattering at the scattering centers (3), the average beam path (x) of the near infrared laser radiation (4) coupled into the workpiece (1) is extended in the direction of the workpiece thickness (D), and by this means the workpiece (1) transmits in total at most 50% of near infrared laser radiation (4) compared to the material (2) at a material thickness corresponding to the workpiece thickness (D), wherein for the wavelength (λ) of the near infrared laser radiation (4), the specific coefficient of absorption of the scattering centers (3) is not higher than the specific coefficient of absorption of the material (2). |
