phenomenon. The application of various plumes showed this
enhancement only in a few plasmas, although much more plasmas
were reported as suitable for resonance enhancement in the case
of femtosecond broadband pulses. These observations show that
atomic number does not play a significant role in classification of
harmonic properties of the plasma media. The important parameter
here could be a second ionization potential of the used species.
A few properties of the generating harmonics from metal-ablated
plasmas were analyzed in
