Laser radar is widely used in unmanned driving, surveying, and mapping, etc. In order to reduce power consumption, cost, and volume, pulsed semiconductor laser has become the first choice of laser drive circuit. Under this background, an optimal design of narrow pulse and large current semiconductor laser drive circuit is completed with inductor as energy storage element. Based on the working principle of the driving circuit in detail, the influence relationship between the value of the energy storage inductor and the power consumption of the circuit is emphatically studied. The driving circuit simulation model was established by using ORCAD PSPICE simulation software, and the main factors affecting the pulse width, peak value, and wave oscillation of the pulse current were summarized. The test results show that the power loss of the energy storage inductor is 59 mW, the pulse width of the driving circuit is 3.8 ns, the rising edge is 3.5 ns, the falling edge is 3.7 ns, the peak current is 132 A, and the peak optical power of the laser output is about 326 W at 10 kHz.
