    摘要: A laser spark plug is described, in particular for an internal combustion engine of a motor vehicle, having a combustion chamber window situated in an end area facing the combustion chamber. Arrangement is provided for cooling a volume region present in the area of the combustion chamber window and/or a medium present in the volume region. The cooling arrangement has 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 is designed essentially annularly. An inner diameter of the cooling body in the area of a front side facing the combustion chamber of the cooling body is smaller than an inner diameter of the cooling body in the area of a front side of the cooling body facing away from the combustion chamber.

    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.
