Combustion engine comprising a laser ignition system

摘要

The engine has a laser light generation device, which is formed to release a laser light with a temporally changing transverse mode structure. A lens (28) is arranged in a central region (29) so that pumping light (25) concentrates on a laser medium (4). A fuel-air mixture is introduced into a combustion chamber. The device has a laser resonator, which is operable in reference of two modes of different transverse order of the released laser light. Independent claims are also included for the following: (1) a laser light regeneration device for an internal combustion engine (2) a method for ignition in a combustion chamber of an internal combustion engine.
