E. Miura et al., IONIZATION BALANCE OF 10PS KRF LASER-PRODUCED PLASMAS, Progress in crystal growth and characterization of materials, 33(1-3), 1996, pp. 269-272
Ionization balance of 10ps KrF laser produced plasmas was investigated
under various irradiation conditions. From the laser intensity depend
ence of relative conversion efficiencies of emissions from F-like and
Ne-like Ge ions, it was found that higher ionization state was realize
d, when a prepulse ASE(amplified spontaneous emission) accompanying a
10ps pulse was suppressed. The absolute conversion efficiency of X-ray
s from 6 Angstrom to 9 Angstrom was also estimated.
