Spontaneous magnetic fields in laser-produced plasmas.
TL;DR: In this article, the authors explain the spontaneous generation of magnetic fields in a laser-produced plasma using thermoelectric currents associated with large temperature gradients near the target, using a variety of targets and background pressures.

Faraday-Rotation Measurements of Megagauss Magnetic Fields in Laser-Produced Plasmas
J. A. Stamper,Barrett H. Ripin +1 more
TL;DR: In this paper, magnetic fields in the megagauss range have been observed in the laser-produced plasma near the focus of a high-power laser pulse, and faraday-rotation measurements utilizing the light of a probing beam and the specularly reflected laser light both show the presence of these large fields.

A. Sullivan,Jill P. Dahlburg,John H. Gardner,Y. Chan,A. V. Deniz,J. Hardgrove,T. Lehecka,M. Klapisch +20 more
TL;DR: In this article, the authors present the performance of the Nike laser in producing uniform illumination and its performance in correspondingly uniform acceleration of targets, and show that the Nike has spatially uniform ablation pressures (Δp/p < 2%).

Laser‐plasma interaction and ablative acceleration of thin foils at 1012–1015 W/cm2
B. H. Ripin,R. Decoste,S. P. Obenschain,Stephen E. Bodner,E. A. McLean,F. C. Young,Robert R. Whitlock,C. M. Armstrong,J. Grun,J. A. Stamper,Steven H. Gold,D. J. Nagel,Robert Lehmberg,J. M. McMahon +13 more
TL;DR: In this article, the interaction physics and hydrodynamic motion of thin-foil targets irradiated by long, low-flux Nd-laser pulses (3 nsec, 1012-1015 W/cm2) are studied experimentally and compared with theoretical models.
