In a method for operating an ignition device for an internal combustion engine, in particular of a motor vehicle, having a laser device which includes a laser-active solid having a passive Q-switching system as well as an optical amplifier connected downstream from the passive Q-switching system (), the laser device generates a laser pulse for radiating into a combustion chamber, and the ignition device having a pump light source which provides a pump light for the laser-active solid and the optical amplifier () of the laser device. The energy of the laser pulse is controlled by varying a wavelength of the pump light.
