Abstract: A driving method of high power pulsed laser is introduced. By analyzing the energy storage characteristics and working principle of the energy storage element, the driving circuit of the energy storage type high power pulse laser is proposed and designed. The high repetition frequency pulse output is realized through the external signal driven MOSFET, and the driving performance of 25ns pulse width and 30A current is achieved. Using Multisim simulation analysis, the circuit principle is verified, the circuit parameters are optimized, and the actual circuit is tested at last, which is identical with the simulation results. This circuit realizes the design of energy storage high power pulse laser drive circuit by means of inductive energy storage conversion and energy storage release, which has wide application value in low voltage environment circuit.
