The circuit has a control stage (4) for a MOS-FET (10) that connects the laser diode (1) to a storage capacitor (9) that is charged to a suitable high voltage, whereby the capacitor discharge current flows at least partly through the laser diode. The laser diode is arranged in a damped L:C resonant...
