Experiments with laser-produced plasmas: electrons, ions, and neutrons
From third workshop on laser interaction and related plasma phenomena; Troy, New York, USA (13 Aug 1973). Experimental re sults, 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 mu m) laser delivering focal spot intensities of greater than 10/sup 16/ W/cm/sup 2/ are reviewed. Preliminary experiments with a 10 J, 1 nsec C0/sub 2/ (10.6 mu m) laser delivering ~ 10/sup 14/ W/cm/sup 2/ 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. (auth)
