We observed the extended harmonic spectra generated in the Cd and Cr plasmas. The mechanism of harmonic extension was attributed to the harmonic generation in doubly charged particles and the influence of broadband ionic resonances in the range of 20–25 nm. The extension of harmonic cutoff up to the 73rd (Cd) and 83rd (Cr) orders was achieved.
