130 High-Order Harmonic Generation in Plasma Plumes Using Picosecond Pulses
Figure 4.12 Harmonic spectra from the (a) Sn, Pb, and Sn:Pb (5:3) alloy
plasmas, and (b) Cu, Zn, and Cu:Zn (65%/35%) alloy plasmas. Reproduced

spectra from lead plasma while adding different gases in the
vacuum chamber, thus changing the components inside the plasma
plume.
Figure 4.12a shows the HHG spectra obtained in the Sn, Pb,
and Sn/Pb alloy plasma plumes. The harmonics from tin plasma
(Fig. 4.12a, upper panel) showed a gradual decrease of each
