摘要： The invention relates to an ignition system (100), in particular for an internal combustion engine (10) of a motor vehicle, comprising a laser spark plug (110), a pump module (120) for supplying the laser spark plug (110) with pump radiation (60) and a light guide device (130) for transmitting the pump radiation (60) from the pump module (120) to the laser spark plug (110). According to the invention, at least two signal transmission devices (140, 150) which are separate from each other and which each extend at least partially along the light guide device (130) as well as an evaluation unit (160) are provided. Said evaluation unit is designed to apply one test signal to each of the signal transmission devices (140, 150), to assess a response signal of the signal transmission devices (140, 150) as a result of the respective test signal, and to conclude from the response signal to an operating state of the corresponding signal transmission device (140, 150).

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) arranged in an end region (100a) facing toward a combustion chamber. According to the invention, means (130) are provided for cooling a volume region (210) situated in the region of the combustion chamber window (120) and/or for cooling a medium situated in the volume region (210). The means for cooling (130) have a cooling body which has material with relatively high thermal conductivity, in particular with a thermal conductivity of approximately 90 watts per kelvin-meter at room temperature or higher. The cooling body (131) is formed substantially in the shape of a circular ring. An inner diameter (D1) of the cooling body (131) in the region of an end side (131a) of the cooling body (131) facing toward the combustion chamber is smaller than an inner diameter (D2) of the cooling body (131) in the region of an end side of the cooling body (131) facing away from the combustion chamber. Heat conducting means (140) are provided which permit a dissipation of heat from an end region (100a) of the laser spark plug (100) facing toward the combustion chamber in the direction of an end region (100b) facing away from the combustion chamber.

摘要： The invention relates to an ignition device (27), in particular for an internal combustion engine of a motor vehicle, comprising a laser device (26) for generating laser pulses (24), and an optical fiber device (280) that is at least optically connected to the laser device (26) to apply pumping light (60) to the laser device (26). According to the invention, the optical fiber device (280) is designed and arranged in the region of the laser device (26) in such a way that radiation (70) which is incident in the region of the laser device (26) and/or in the region of a combustion chamber (14) associated with the laser device can be injected into the optical fiber device (280). The disclosed design and arrangement of the optical fiber device advantageously allow the radiation that is injected into the optical fiber device to be analyzed, in particular by a detector that is disposed at a distance, without having to provide additional, separate optical fiber devices for the radiation that is to be analyzed, because the radiation that is to be analyzed can be guided directly via the same optical fiber that is used for supplying the pumping light.
