Patent ID: 8146554

Claim:
A laser ignition apparatus, comprising: at least two laser light generating devices; a common optical coupling-in means for coupling laser light from the at least two laser light generating devices into a combustion chamber of a combustion machine; and mirrors for deflecting the laser light from the at least two laser light generating devices, the mirrors being disposed between the at least two laser light generating devices and the optical coupling-in means, wherein the at least two laser light generating devices are arranged such that an exit surface of a first one of the laser light generating devices and an exit surface of a second one of the laser light generating devices are disposed at an angle different from 0° relative to each other, and wherein the at least two laser light generating devices are arranged such that the laser light given off by the at least two laser light generating devices in the operating condition impinges on the optical coupling-in means or issues from the optical coupling-in means in a parallel displaced relationship or at an angle to each other.
