Abstract

In recent papers^1,2 we proposed dual-wavelength-pumped Raman-resonant four-wave mixing (FWM) where the primary pump (P1) energy can be concentrically converted into its anti-Stokes field AS1(P1), or vice versa, under the phase-matched wave-vector configuration shown in Fig. 1. In this paper we show theoretically that this process is applicable to the generation of intense picosecond pulses in the VUV region, where most of the pulse-length-control devices, such as Pockels cells and saturable absorbers, cannot be used.
