The development of the generation of coherent VUV/XUV radiation by nonlinear optical process

Recent progress in both experimental and theoretical research on the generation of coherent VUV/XUV radiation by nonlinear optical process isreviewed. After some background introduction a series of widely used nonlinear optical proce-ses such as two-photon-resonant four-wave-mixing(TFWM) in metal vapors, non-resonant four-wave-mixing(NFWM), TFWM and the high-order harmonic genera-tion in rare gases is dicussed.At the end of this paper some basic applications of coherent VUY/XUV radiation are presented and near-term prospects are predicted.
