Abstract: A laser spark plug device for an internal combustion engine includes a prechamber for receiving an ignitable medium and at least one overflow channel providing a fluid connection between an internal space of the prechamber and an external space surrounding the prechamber. The at least one overflow channel is configured such that when a fluid flows through the overflow channel into the internal space of the prechamber, the result is a fluid flow having at least one eddy which rotates on an eddy axis forming an angle of more than approximately 45° with a longitudinal axis of the laser spark plug device.
