    Abstract

    Double circuit synchronous closed-loop design based on precise laser pulse waveform shaping and energy stability control was introduced. A pulse shaping closed-loop control system was established between arbitrary waveform generator and the output of preamplifier system, and an energy stability closed-loop system was established between polarization large-mode-area fiber amplifier and the regenerative amplifier. The laser pulse’s precise shaping with high energy stability was demonstrated based on the Integration Test Bed. And the closed-loop accuracy of the pulse waveform was better than 2% (RMS), and the energy stability was better than 5% (PV). The results were successfully applied to the formal launch of physical experiments, and the power accuracy of the conventional shaping pulse waveform was better than 2%. The successful demonstration of the double circuit synchronous closed loop system strongly supports the precise control design of the laser parameters of laser driver for ICF.
