Abstract
The invention relates to a laser assembly, wherein, in one embodiment, the laser assembly () comprises a plurality of laser groups () each having at least one semiconductor laser (). Furthermore, the laser assembly () contains a plurality of photothyristors (), each laser group () being clearly assigned one of the photothyristors (). The photothyristors () are each connected electrically in series with the associated laser group () and/or integrated in the associated laser group (). Furthermore, the photothyristors () are each optically coupled to the associated laser group (). A dark breakdown voltage (Ut) of each photothyristor () lies above an intended operating voltage (Ub) of the associated laser group ().
