Experiments with Laser-Produced Plasmas: Electrons, Ions, and Neutrons

  • R. P. Godwin

Abstract

Experimental results, particularly x-ray bremsstrahlung and ion time-of-flight measurements, obtained from plasmas generated with a 10 J, 25 psec Nd:YAG-Nd:glass (1.06 μm) laser delivering focal spot intensities of greater than 1016 W/cm2 are reviewed. Preliminary experiments with a 10 J, 1 nsec CO2 (10.6 μm) laser delivering ~ 1014 W/cm2 to a target are briefly discussed. Both sets of experiments yield high-energy (tens of keV) electrons and ions. Experimental evidence indicates that neutron emission can be explained by electron heating and a consequent ion acceleration. Therefore, neutron production in laser-produced plasmas can be a delusive diagnostic.
