Abstract

A laser spark plug, e.g., for an internal combustion engine of a motor vehicle or a heavy-duty gas engine, has an antechamber for receiving an ignitable medium and a combustion chamber window which separates the antechamber from a part of the laser spark plug facing away from the combustion chamber. At least one flow-guiding element is provided in the antechamber and is situated in such a way that it deflects a fluid flow, which occurs in the antechamber and moves toward the combustion chamber window, into a radially inner direction.
