Abstract

We report what is to our knowledge the first generation of femtosecond VUV radiation tunable in the spectral range from 102 - 124 nm generated by two photon-photon resonant and near resonant four-wave difference-frequency mixing ((omega) _DF equals 2(omega) _P - (omega) ₁) in krypton and argon. The FWDFM process was pumped by intense 250 fs, 193 nm pulses ((omega) _P) derived from the 80 fs output pulses of a 0.1 TW Ti:sapphire laser system by cascaded fourth harmonic generation in three BBO crystals and subsequent amplification in an ArF gain module. The synchronized injection pulses ((omega) ₁) were generated in an travelling wave optical parametric system driven by the second harmonic of the Ti:sapphire output. Frequency up-conversion of the pulses at (omega) ₁ allows the extension of the tuning range also to lower frequencies at (omega) _D.
