Abstract
Frequency up-conversion of XeCl-laser radiation (308 nm) and KrF-laser radiation (249 nm) by two-photon resonantly enhanced four-wave mixing in Mg vapor is reported. A dye laser tuned to two-photon resonance with the 3s–3d1D2 Mg level was used. The dependences of generated signals at 127 and 115 nm on input intensity and number density were investigated. No saturation was observed up to 4 × 109 W/cm2 (249 nm) and 6 × 108 W/cm2 (308 nm). The 115-nm signal was phase matched by using Xe. Conversion efficiencies and signal linewidths are discussed.Keywords
