Abstract

We have performed high-resolution, extreme-ultraviolet spectroscopic measurements of both spherically expanding plasmas and planar-expanding plasmas, produced by using the Omega laser system in spherical illumination geometry and line-focus geometry. Direct comparison of spectral lines from these two types of plasma shows enhanced broadening of emission lines from the sperical plasmas. This broadening is attributed to Doppler shifts from large ion expansion velocities. A hydrodynamic code for laser-produced plasmas is used together with an atomic postprocessor to calculate output-line intensity profiles. Simulated line profiles are compared with experimental line profiles and show good agreement.
