The semiconductor laser driver includes a control unit for controlling an input drive signal, electric power conditioning and pulse charging unit for receiving the drive signal controlled in the control unit and thereby generating an electrical energy, energy storage unit for receiving the electrical energy from the 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 the high current impulse received from the optically activated semiconductor switch unit into a high power, optical pulse to be outputted. The optically activated semiconductor switch unit is a three terminal switch comprising first switch made by two of three electrodes to have a nip structure and second switch made by one of two electrodes of first switch and remaining one of three electrodes to have pip structure.
