Abstract
A laser pulse generator which consists of charging resistor, energy storage capacitor laser diode, and switching elements was designed in order to generate 15ns, 20W laser pulses. And the effects of performances of SCR and FET as switching elements are compared. When SCR is used, the SCR's low maximum voltage makes the circuit so complicated, and when FET is used, the FET needs the special sate driver which improves the FET's operation.
