Abstract
A laser spark plug for an internal combustion engine having a laser device, which includes a laser-active solid and a passive Q-switch, and having a pumped light source, which is configured to generate pumped radiation and to irradiate it onto the laser device. The pumped light source has a plurality of individual pumped light emitters at least two pumped light emitters each being activatable separately from one another.
