Abstract: Emissions of fast ion and neutral debris from laser-produced lithium plasmas have been investigated. We found that Li + , Li 2+ , and Li 3+ ion energy spectra look similar. The peak positions and maximum energies in their energy spectra were about 700–800 eV and about 800–900 eV, respectively, which were much lower than those of such high-Z targets as Xe and Sn. These indicate that most of the fast Li + and Li 2+ ions were produced by the recombination of Li 3+ ions while the plasma expanded, and that they were not accelerated to a high energy range as much as the high-Z targets. We did not observe any fast neutral Li atoms. These results suggest that the use of the Li target for the extreme ultraviolet (EUV) source would be advantageous for practical applications.
