Abstract

A laser spark plug, in particular for an internal combustion engine, having an arrangement or structure for coupling, especially focusing, laser radiation in or on an ignition point, including an arrangement or structure for influencing a fluid flow disposed in an end region of the laser spark plug on the side of the combustion chamber, which constitute an essentially sleeve-shaped extension of the laser spark plug in the direction of the combustion chamber, in which the arrangement or structure for influencing the fluid flow is configured to influence the fluid flow in the region of the ignition point.
