Abstract (en)
[origin: WO2008000585A1] The invention relates to a method for operating an ignition device for an internal combustion engine (10), in particular a motor vehicle. Said ignition device has a laser device (26) that comprises a laser-active solid body (44) provided with passive Q-switching (46) and an optical amplifier (70) that is arranged downstream from the passive Q-switching (46), said laser device producing a laser pulse (24) for radiating in a combustion chamber (14). Said ignition device also comprises a pump light source (30) which provides a pump light (60) for the laser-active solid body (44) and the optical amplifier (70) of the laser device (26). According to the invention, the energy of the laser pulse (24) is controlled by changing a wave length of the pump light (60).
