ABSTRACT:
In order to generate precisely square-wave laser light pulses, a laser diode is fed by a current pulse generator which comprises a timing pulse generator and a power stage, which is driven by the latter and which is followed by a single-pole driver stage of high current having a rise time of a few nanoseconds for the laser diode which is connected in the circuit of a battery of capacitors.
