Method and device for igniting a fuel-air mixture in a combustion chamber of an internal combustion engine

摘要

A device is provided for igniting a fuel-air mixture in a combustion chamber of an internal combustion engine with the aid of electromagnetic radiation, in particular light. The device includes at least two laser radiation sources, each having an optical resonator. The resonators are spatially oriented with respect to one another in such a way that modes of the laser radiation sources are coupled to one another and are able to generate time-shifted pulses of the electromagnetic radiation.
