Abstract To intelligently control the parameters of a semiconductor pulsed seed source, a novel scheme is presented involving commercial electronic chips as switching devices to drive a semiconductor laser (SL). By combining theoretical analysis and rate-equation theory, we construct a mathematical model of the SL. Further, a pulsed laser module with real-time tunable optical pulse parameters is designed and implemented. The tunable pulse width ranges from 90 ps (PS) to continuous wave, and the tunable pulse repetition rate is 0–10 MHz. the SL temperature drift is less than 0.07 °C. The experimental results verify the feasibility of the design scheme, and the theoretical analysis and simulation results guide the generation of high-quality optical pulses.
