Abstract :
Phase matching is indispensible for the efficient generation high-order harmonic radiation (HHG), especially in the range of several-100-eV. Recently it has been theoretically predicted that perfect pressure induced phase matching cannot be realized in helium in the 0.2-1 keV spectral range using 800 nm light pulses. In this contribution, a detailed experimental study of the phase mismatch is presented for the first time and guidelines for maximizing the short wavelength signal without perfect phase matching are derived.
