光致电离等离子体是宇宙中等离子体的一种重要的存在形式，这种等离子体是一些高能天体 发射很强的辐射场照射周围的稀薄等离子体产生的。随着高能量密度物理的发展，2009 年 Fujioka 等人使用高功率激光装置（GEKKO-XII 激光装置）制造出光致电离硅等离子体，并观测到类似 于天文观测中的 X 射线光谱。本综述重点总结了 Fujioka 实验以来，各理论工作对实验中 X 射 线光谱的模拟结果，并对光致电离等离子体光谱实验方面的研究进行展望。本文期望为相关研究 人员深入理解光致电离等离子体光谱发射的物理机制提供参考。

Photoionized plasma is an important form of plasma in the universe, which is produced by some high-energy celestial bodies emitting strong radiation fields to irradiate the surrounding thin plasma. With the development of high energy density physics, the photoionized plasma can be produced in laboratory. In 2009, Fujioka et al. used the GEKKO-XII laser facility to produce photoionzed Si plasma, and observed X-ray spectrum similar to that in astrophysical environment. This paper reviews the main theoretical simulation results for the experimental X-ray spectrum since this photoionization experiment, and proposes the future research direction on the photoionized plasma. This review aims to provide a reference for researchers in related fields and deepen their understanding of the physical mechanism of photoionized plasma
