A high power, high PRF, pulsed laser diode driver including an optically activated three terminal semiconductor switch, capable of generating high peak power light pulses with an ultra-narrow pulsewidth at a high PRF. 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 recelved 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 optically activated semiconductor switch unit is a three terminal switch consisted of three electrodes.
