F., et al., Picosecond X-Ray Laser Interferometry of Dense Plasmas, Physical Review Letters 89, no. 6 (5 August 2002): 065004-1-065004-4.http://hdl.handle.net/10217/67634We 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 μm 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.born digitalarticleseng©2002 American Physical Society.Copyright and other restrictions may apply.
