Abstract

Coherent radiation at various VUV wavelengths, e.g., 125.9, 126.1, and 125.4 nm, has been generated through four-wave mixing processes enhanced by two-photon resonances in xenon. Maximum efficiencies of the order of 10⁻⁴ were achieved. Maximum output intensities of difference generation (2ω₁ − ω₂) for 7p[0½]₀, 7p[1½]₂, and 6p′[1½]₂ resonant states occurred at xenon pressures of 24, 12.5, and 4 Torr, corresponding to values of phase mismatch per atom of 1.2 × 10⁻¹⁸, 2.3 × 10⁻¹⁸, and 7.1 × 10⁻¹⁸ esu, respectively. Parametric generation at 117.0 nm through the ${7s\left[1\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.\right]}_1^{°}$ state was also observed.
