Abstract

A laser spark plug for an internal combustion engine has at least one laser unit for guiding, shaping, and/or for producing laser radiation, a combustion chamber window, and a housing which has, at the side of the combustion chamber window situated opposite the laser unit, a screen for the passage of the laser radiation guided, shaped, and/or produced by the laser unit into a combustion chamber, the screen having a first end facing the combustion chamber and a second end facing away from the combustion chamber, the inner contour of the screen having an extremal cross-section in a region that is situated at a distance both from the first and second ends.
