    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°.

    摘要： The invention relates to a laser spark plug (100), in particular for an internal combustion engine of a motor vehicle, having a combustion chamber window (120) situated in an end area (100a) facing the combustion chamber. According to the invention, arrangement (130) are provided for cooling a volume region (210) present in the area of the combustion chamber window (120) and/or a medium present in the volume region (210). The cooling arrangement (130) have a cooling body which has material having a relatively great thermal conductivity, in particular having a thermal conductivity of approximately 90 Watts per Kelvin and meter at room temperature or more. The cooling body (131) is designed essentially annularly. An inner diameter (D1) of the cooling body (131) in the area of a front side (131a) facing the combustion chamber of the cooling body (131) is smaller than an inner diameter (D2) of the cooling body (131) in the area of a front side of the cooling body (131) facing away from the combustion chamber. Heat-conducting arrangement (140) are provided which enable a heat dissipation from an end area (100a) of the laser spark plug (100) facing the combustion chamber in the direction of an end area (100b) facing away from the combustion chamber.
