Abstract

We propose a method of producing VUV even in positively dispersive media by the addition of a strong saturating resonant laser field. This method of changing dispersion provides in general more than one frequency region in which efficient VUV generation can take place. In fact the generation can take place in the region where it was ordinarily forbidden. The proposed method can have practical advantage as both the intensity and the frequency of the saturating field can be used to control the dispersion and thus provides one with greater flexibility.
