The application provides a control system of a laser pumping source constant current driver and a DSP digital processing chip, the control system of the laser pumping source constant current driver is realized based on the DSP digital processing chip, a control loop capable of generating and outputting a driving PWM signal is arranged in the DSP digital processing chip, a closed-loop, digitally designed voltage control loop and a current control loop are arranged in the control loop, and the voltage control loop and the current control loop alternatively output driving control PWM signals. The application has the beneficial effects that the rising and falling edge time of the output current is faster, the current dynamic overshoot is lower, and the device output is stable and free of oscillation.
