The compact high energy DPSSL driving circuit system

In order to satisfy the requirements of laser irradiation and laser ranging over the long distance, and to realize the miniaturization, the modularization and the engineering application of 1J high-energy DPSSL circuit system, a laser driving circuit system is designed according to the laser work patterns of one oscillator stage and two amplification stages. The system includes many parts, such as the integrated power supply circuits, the corresponding LD drivers of three stages, the signal control circuits, the Q switched circuits, the receiving circuits and the temperature control circuits, etc. It possesses the characteristics of 28VDC input power source, working frequency 25Hz，driving laser output 1J, working stable and reliable, thermal management optimization and small size as well as light weight. The study promotes the comprehensive technical specifications of the platform load effectively and can also provide a valuable reference for the miniaturization of high energy DPSSL circuit system.
