Emission spectra of the He gas plasma when only the first laser with an energy of 82 mJ is focused onto different sub-targets; (A) LiF, (B) Al, and (C) Pb in the surrounding He gas at 3 kPa. Inset shows a photograph of the produced plasma. The gate delay and gate width of the detection system were set as 200 ns and 50 μs, respectively, after the initiation of the first laser (T triplet, S singlet).
