随着惯性约束聚变（ＩＣＦ）研究的深入发展，物理实验对激光驱动器系统有了更高的要求．为了确保激光驱动器安全运行在高功率密度下，需要高填充因子并避免强烈的衍射．追求大的填充因子和近场光场均匀是矛盾的两个方面，平顶超高斯光束较好地解决了此矛盾，研制平顶高斯型锯
With the development of inertial confinement fusion (ICF), physical experiments have higher requirements for laser driver system. To ensure safe operation of the laser driver at high power densities, a high fill factor is required and strong diffraction avoided. Pursuit of large fill factor and near-field uniform light field are two contradictory aspects of the flat-topped super-Gaussian beam to better solve this contradiction, the development of flat-top Gaussian Saw
