Abstract : Extreme VUV radiations may be produced by harmonic generation in rare gases exposed to intense laser fields. Possibilities and limitations will be discussed. The absorption of a large number of photons by an atomic system may lead to very interesting features, and significant advances have been made in this domain: above threshold ionization, multiply charged ion production and more recently high order harmonic generation. As far as harmonic generation is concerned, most of the experiments in a gaseous medium use short incident wavelength in order to obtain the shortest generated wavelength. The purpose of the present paper is to discuss some VUV or XUV light emission by harmonic generation in a rare gas medium irradiated by an intense 1064 nm laser field.
