摘要 结合快点火靶丸预压缩涉及的基本物理问题,分析了驱动激光脉冲波形对材料压缩过程的影响,并利用辐射流体力学程序MULTI模拟了不同激光波形下的材料压缩情况。结果表明:通过调节激光脉冲波形,优化激光初始强度、激光强度开始上升时间和上升速度,控制压缩过程中的熵增,可以获得更高的材料压缩度。 To better understand the basic physics of fast ignition target compression, the effects of laser pulse shape on the compression of flat target are analyzed and simulated using hydrodynamic code MULTI. Results show that high material density can be achieved through optimizing the initial intensity, rising time and the intensity slope of the laser pulse.
