准分子激光在惯性约束核聚变(ICF)和等离子体物理等领域具有巨大应用潜力,是ICF激光驱动器的主要备选方案。适合ICF实验研究的激光脉冲宽度约1～10ns,而准分子激光器的脉冲宽度通常在20～30ns。物质状态方程(EOS)的实验研究对辐照光脉冲时间形状也有特殊要求。因此,需要开展准分子激光脉冲压缩技术研究。在激光脉冲形成过程中,激光腔长和激光腔内上能级粒子分布是影响输出脉冲宽度的两个因 Excimer lasers have great potential for applications in the fields of inertial confinement fusion (ICF) and plasma physics and are the main options for ICF laser drivers. The laser pulse width suitable for ICF experiments is about 1 ~ 10ns, while the excimer laser pulse width is usually 20 ~ 30ns. The experimental study of EOS also has special requirements on the time shape of irradiated light pulse. Therefore, the need for excimer laser pulse compression technology research. In the process of laser pulse formation, the length of the laser cavity and the distribution of upper-level particles in the laser cavity are two factors that affect the output pulse width
