Tunable femtosecond vacuum-ultraviolet radiation in the range ωD = 102–124 nm has been generated by two-photon-resonant and near-resonant four-wave difference-frequency mixing (wD = 2ωp − ωI) in krypton and argon by use of intense 250-fs ArF laser pulses (ωp) and tunable femtosecond signal and idler pulses (ωI) generated by an optical parametric generator.
