A high power optical pulse generator is proposed and experimentally validated.The temperature of this system is accurately cotrolled by using the optimization PID parameter,and peak power of optical pulse is adjusted by an automatic power closed-loop control.The experiment results demonstrate that our system can realize 4.8W peak power and 760ps response time of the output optical pulse.Additionally, the system is highly integrated, which can be widely used in optical fiber sersor system.
