我们提出的第一个结果从皮秒密集的激光产生的等离子体使用软x射线激光干涉。皮秒的持续时间和短波长的14.7纳米镍类钯激光器减轻了与运动模糊和折射通过毫米级等离子体相关的影响。这使得能够直接测量目标表面10微米内的电子密度分布。一系列高质量的二维（2D）密度测量提供了明确的表征的时间演变在一个快速发展的等离子体适用于验证现有的1D和2D流体动力学代码。
We present the first results from picosecond interferometry of dense laser-produced plasmas using a soft x-ray laser. The picosecond duration and short wavelength of the 14.7 nm Ni-like Pd laser mitigates effects associated with motion blurring and refraction through millimeter-scale plasmas. This enables direct measurement of the electron-density profile to within 10 microm of the target surface. A series of high-quality two-dimensional (2D) density measurements provide unambiguous characterization of the time evolution in a fast-evolving plasma suitable for validation of existing 1D and 2D hydrodynamic codes.
