Dynamics of the critical surface in high-intensity laser-solid interactions: Modulation of the XUV harmonic spectra
Physical Review Letters 88:15 (2002) 1550011-1550014
Abstract:
The generation of harmonics from the interaction of an intense (I 鈮 1018 W cm-2) laser with a solid surface was discussed. At higher laser intensities, the modulation of the harmonic emission spectrum with a periodicity of two to four harmonics was observed. The results showed that the dynamics of the critical surface can be inferred from the shape of the harmonic spectrum.Nuclear diagnostics of high intensity laser plasma interactions

Characterization of a gamma-ray source based on a laser-plasma accelerator with applications to radiography
Applied Physics Letters 80:12 (2002) 2129-2131
Abstract:
The application of high intensity laser-produced gamma rays is discussed with regard to picosecond resolution deep-penetration radiography. The spectrum and angular distribution of these gamma rays is measured using an array of thermoluminescent detectors for both an underdense (gas) target and an overdense (solid) target. It is found that the use of an underdense target in a laser plasma accelerator configuration produces a much more intense and directional source. The peak dose is also increased significantly. Radiography is demonstrated in these experiments and the source size is also estimated. 漏 2002 American Institute of Physics.Response to 鈥淐omment on 鈥楥ollisionless shock and supernova remnant simulations on VULCAN鈥 鈥 [Phys.
