Abstract: Herein, a set of semiconductor laser pulse seed sources based on an embedded chip is proposed. Its greatest feature is that the optical pulse frequency and pulse width can be independently adjusted in real-time. The pulse seed sources can be switched independently and online from the gain-switched mode to the quasi-continuous wave mode to obtain optimal optical parameters for specific applications. To explore the physical mechanism of the semiconductor laser source, the rate equation that describes the carrier-photon transient change in a semiconductor laser cavity is numerically derived and solved. Subsequently, problems to consider while designing the drive circuit were identified. The system evaluation indicated that the optical pulse frequency adjustment range was 250 Hz–42 MHz, and the narrowest optical pulse output width was 80 ps. The pulse seed sources
can drive semiconductor lasers with different central wavelengths (1064 nm, 1550 nm, and 1970 nm), which can also simultaneously
drive two semiconductor lasers and output dual-band optical pulses. It can be used as a seed source for general high-power
optical systems and exhibits good application value and extensive market prospects.
