Abstract

Vacuum-ultraviolet (VUV) generation by resonant third-order sum–difference frequency conversion (w_VUV = 2w_R − w_T) in krypton has been investigated. The frequency w_R (λ_R = 212.55 nm) was resonant with the Kr two-photon transition 4p–5p[1/2, 0]. By tuning w_T in the range λ_T = 220–860 nm it was possible to generate w_VUV in the wavelength range λ_VUV = 200–120 nm. The conversion efficiency was enhanced in the range 121–123 nm by phase matching with a normally dispersive buffer gas (Ar); under the best phase-matched conditions employed, VUV output powers at the Lyman-α wavelength of the order of 1 kW were inferred from the estimated VUV pulse energy. This source was used to measure high-lying members of the Mg principal series near 162 nm. High resolution and excellent sensitivity of detection, when a thermionic diode detector was used, have been demonstrated.
