    摘要： A laser spark plug configured to be installed into a plug shaft of an internal combustion engine, and to focus laser ignition energy into the combustion chamber via combustion chamber-side, and thus proximal end, of the laser spark plug has, at a distal end of the laser spark plug opposite to the proximal end, a connecting unit for detachable mechanical and thermal connection to a cooler, the connecting unit being designed to permit the connecting and the disconnecting of the cooler when the laser spark plug is installed in the plug shaft.

    摘要： A cooling device for a laser spark plug. The cooling has a radially inner first contact area which is developed to establish a thermal contact to a housing of the laser spark plug via at least one first radially inner contact surface. The cooling device also has a radially outer second contact area which is developed to establish a thermal contact to a heat sink, in particular to an inner wall of a spark plug hole receiving the laser spark plug, via at least one first radially outer contact surface. A connector is provided, which is developed to establish a thermal contact between the first contact area and the second contact area. The cooling device is developed at least in part elastically in order to allow for a relative movement in a generally radial direction between at least the first contact surface and the second contact surface.

    摘要： A laser spark plug for an internal combustion engine includes at least one element for guiding, shaping and/or generating laser radiation, a combustion chamber window and a housing. The housing has, on the opposite side of the combustion chamber window from the element, an aperture for the passage of the laser radiation guided, shaped and/or generated by the element into a prechamber disposed at the end of the housing on the combustion chamber side. At least one overflow channel is provided for a fluid connection between an internal space of the prechamber and a combustion chamber surrounding the prechamber. When a fluid flows into the internal space of the prechamber through the overflow channel, a fluid flow is obtained that enters the interior of the aperture at a minimum angle ε, in particular measured with respect to the longitudinal axis of the laser spark plug, of 45°.
