Aiming at the characteristics of low relative load capacity and small volume capacity of helicopter platform, and to achieve the purpose of efficient pumping of airborne pulse laser media, an integrated structural design method was adopted to design an efficient pulse power supply system that provides pumping energy for pulse xenon lamps of podded lamp-pumping solid-state laser. Theoretical analysis and experimental verification were conducted on the discharge characteristics and device parameters of xenon lamps, and the key device parameters of discharge main circuit of xenon lamp were obtained. A principle prototype was trial-produced, and joint debugging experiments were conducted. The results show that the actual test data are basically consistent with the theoretical data, and the discharge loop parameters of the pulse power supply system are designed reasonably. The total mass of the power supply system is about 48 kg, the capacitor charging time is 3.76 s, the peak discharge-current of xenon lamp is 3.6 kA, and the pulse width is 1.06 ms, respectively. After adopting the integrated structural design method, the volume and weight of the pulse power supply system can meet the requirements of the airborne platform, verifying the feasibility of the key technology.
