Abstract (en)

[origin: WO2009097635A2] Disclosed is a laser ignition device comprising a base (1) and a combustion chamber window (2) for injecting laser light into the combustion chamber (4) of an internal combustion engine. The combustion chamber window (2) rests against a receiving collar (5) of the base (1) in the area of the surface (2a) from which the laser light emerges. By applying pressure, a fastening element (6) fixes the combustion chamber window (2) to the base (1) in the area of the surface (2b) on which the laser light is incident. Said fastening element (6) is designed such that the pressure applied to the combustion chamber window (2) by the fastening element (6) remains substantially constant or is increased when the temperature of the base (1) and/or the combustion chamber window (2) rises. Also disclosed is an internal combustion engine comprising such a laser ignition device.
