Abstract
Methods and apparatuses for laser ignition in an internal combustion engine. Laser radiation is directed to an ignition location within a combustion chamber with adaptive optics, and the position of the ignition location is adaptively adjusted during operation of the engine using the adaptive optics. Multiple ignition locations may be provided during a cycle of an internal combustion engine. A first pulse of laser radiation is directed to a first ignition location within a combustion chamber with adaptive optics, and a second pulse of laser radiation is directed to a second ignition location within the combustion chamber using the adaptive optics.
