An ignition device, in particular for an internal combustion engine of a motor vehicle, having a laser device for generating laser pulses, and having an optical fiber device which is at least optically connected to the laser device for supplying the laser device with pumped light. The optical fiber device is configured and situated in the region of the laser device in such a way that radiation incident in the region of the laser device and/or in the region of a combustion chamber associated with the laser device may be injected into the optical fiber device. The disclosed configuration of the optical fiber device advantageously allow the radiation which is injected into the optical fiber device to be analyzed, in particular using a detector which is remotely situated, without having to provide additional, separate optical fiber devices for the radiation to be analyzed, because the radiation to be analyzed may be conducted directly via the same optical fiber that is already used for supplying pumped light.
