In high order harmonic generation the conversion efficiency of plateau harmonics is limited by absorption. In principle, this limitation may be overcome by parametric amplification. Various schemes of multi-photon pumped "high order parametric amplifiers" (HOPAs) for the short wavelength spectral range have been analyzed, involving gain transfer and coupling processes of different orders [1]. Experimental attempts to realize such processes will be presented and discussed.
