Abstract
A laser spark plug for an internal combustion engine, in particular for a gas engine, comprising a laser crystal integrated into the laser spark plug and a combustion chamber optical means, wherein laser light pulses issuing from the laser crystal can be coupled by way of the combustion chamber optical means into a combustion chamber of the internal combustion engine, an optical laser light sensor being integrated into the laser spark plug, wherein the combustion chamber optical means is provided with a reflection surface which faces towards the laser light sensor—and is preferably curved—and is provided with a reflective mirroring, wherein at least a part of a laser light reflected at the reflection surface during the duration of a laser light pulse can be detected by the laser light sensor.
