A high power, pulsed laser diode driver maintaining high efficiency, light weight and compactness by a provision of an energy storage capacitor of a non-uniform stripline structure with a low impedance. The semiconductor laser driver includes a control unit for controlling an input drive signal, electric power conditioning and pulse charging unit for receiving said drive signal controlled in said control unit and thereby generating an electrical energy, energy storage unit for receiving said electrical energy from said electric power conditioning and pulse charging unit and storing the received electrical energy, triggering light source and drive unit for generating a low power, optical laser light when the electrical energy has been stored in the energy storage unit, optically activated semiconductor switch unit for converting the capacitively charged electrical energy into a high current impulse, and a high power laser array for converting said high current impulse received from said optically activated semiconductor switch unit into a high power, optical pulse to be outputted. The energy storage unit includes an energy storage capacitor of a non-uniform stripline structure with a very low impedance.
