物理实验对神光Ⅱ装置的输出脉冲波形有很高的精度要求。对于单色光,通常做法是利用增益通量曲线反演激光链路获得注入波形,该方法在求解高通量或复杂波形时的精度比较差,甚至对宽带脉冲失效。针对不同输出通量,提出了智能算法和增益通量曲线的分层使用策略并应用于神光Ⅱ全链路的波形反演,混合算法的计算精度理论上取决于采样点数目。通过模拟仿真验证了混合算法具有稳定性好、精度高和收敛快的特点。 The physical experiment has very high precision requirements for the output pulse waveform of SGⅡ. For monochromatic light, it is common practice to gain an injected waveform by inverting the laser link using a gain-fluence curve. This method is less accurate in resolving high-flux or complex waveforms, even for broadband pulses. According to the different output fluxes, a layered strategy of intelligent algorithm and gain flux curve is proposed and applied to the waveform inversion of SG II. The computational accuracy of the hybrid algorithm theoretically depends on the number of sampling points. Simulation results show that the hybrid algorithm has the characteristics of good stability, high precision and fast convergence.
