Abstract: A laser submodule for generating rapid laser pulses comprises a linear array of n lasers. Each laser of the n lasers has an anode and a cathode. Each of the cathodes is electrically connected to a common reference node. The submodule further comprises n charging capacitors. Each charging capacitor is electrically connected to the anode of a corresponding laser of the n lasers through a respective discharging inductance. The laser module further comprises n charging circuits. Each charging circuit is configured to charge one of the n charging capacitors through a respective charging inductance. The charging inductance for each charging capacitor is greater than the discharging inductance for the respective charging capacitor.

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.
