Abstract

We have used a tabletop soft-x-ray laser and a wave-front division interferometer to probe the plasma of a pinch discharge. A very compact capillary discharge-pumped Ne-like Ar laser emitting at 46.9 nm was combined with a wave division interferometer based on Lloyd's mirror and Sc-Si multilayer-coated optics to map the electron density in the cathode region of the discharge. This demonstration of the use of tabletop soft-x-ray laser in plasma interferometry could lead to the widespread use of these lasers in the diagnostics of dense plasmas.

摘要

我们使用了一台桌面型软X射线激光器和一个波前分割干涉仪来探测箍缩放电等离子体。一台非常紧凑的毛细管放电泵浦类氖氩激光器，其发射波长为46.9纳米，与基于劳埃德镜和Sc-Si多层镀膜光学元件的波分干涉仪相结合，以绘制放电阴极区域的电子密度图。这种在等离子体干涉测量中使用桌面型软X射线激光器的演示可能会导致这些激光器在稠密等离子体诊断中的广泛应用。
