Summary:A drive/control circuit for a laser diode arrangement (1) which is arranged in a discharge current circuit of a capacitor arrangement (6) formed by at least one capacitor and in which a DC voltage source (2) is included in a charge-current circuit having at least one inductance (5) which forms part of a series-resonance circuit with a resonance frequency (FR), the half-wavelength of which is equal to the pulse-width of the generated current pulse with a switch (7) closed. Bei einer Ansteuerschaltung zur Ansteuerung einer wenigstens eine Laserdiode aufweisenden Laserdiodenanordnung mit Stromimpulsen ist die Laserdiodenanordnung in einem wenigstens einen steuerbaren Schalter aufweisenden Entladestromkreis eines Kondensators angeordnet, in dessen eine Gleichspannungsquelle einschließenden Ladestromkreis zumindest eine Induktivität derart angeordnet ist, dass diese zusammen mit dem Kondensator zumindest während der Dauer des Stromimpulses als Serienresonanzkreis mit einer Resonanzfrequenz wirkt.
