Abstract
A laser ignition device for an internal combustion engine, in which the laser ignition device has at least one laser spark plug and a cooling device for temperature control, in particular cooling, of the laser spark plug. The cooling device has a cooling circuit, containing a coolant, which is thermally connectable to at least one component of the laser spark plug, a volume of the coolant contained in the cooling circuit being less than or equal to approximately 50% of a compression volume of a cylinder of the internal combustion engine, which may be less than or equal to approximately 10% of a compression volume of the cylinder of the internal combustion engine.
