Abstract
A laser module comprises a plurality of laser submodules with a respective plurality of lasers. Each laser submodule has a driver IC. Each driver IC controls several lasers. The driver ICs of the laser module can use the received signals of photodetectors to homogenize and readjust the real emission amplitude of the laser pulses for all lasers of the laser module and regulate the emission point in time of the respective real laser pulses to a synchronization signal. The driver IC can detect a failure of a laser by the photodetector belonging to it and output an error signal. The lasers directly coupled with the photodetectors in a compact design.
