我们描述了一种软 X 射线激光干涉测量技术，该技术允许以皮秒时间分辨率对等离子体电子密度进行二维诊断。它由坚固的高通量幅分干涉仪和 14.7 nm 瞬态反转软 X 射线激光器组合而成，可产生大约 5 ps 脉冲。由于其皮秒分辨率和短波长可扩展性，该技术有可能将软x射线激光干涉测量的高固有精度扩展到具有重大基础和实际意义的高密度等离子体的研究，例如惯性约束聚变研究。介绍了其在密集的大规模激光产生的等离子体的诊断中的使用结果。
We describe a soft-x-ray laser interferometry technique that allows two-dimensional diagnosis of plasma electron density with picosecond time resolution. It consists of the combination of a robust high-throughput amplitude-division interferometer and a 14.7-nm transient-inversion soft-x-ray laser that produces approximately 5-ps pulses. Because of its picosecond resolution and short-wavelength scalability, this technique has the potential for extending the high inherent precision of soft-x-ray laser interferometry to the study of very dense plasmas of significant fundamental and practical interest, such as those investigated for inertial confinement fusion. Results of its use in the diagnostics of dense large-scale laser-created plasmas are presented.
