Abstract
We describe the application of pulsed free jets for the generation of the third harmonic of laser radiation. Using a supersonic expansion of Xe we have frequency tripled an 18 MW beam at 354.7 nm to obtain 5 x 10" photons/pulse at 118.2 nm, while for CO we have obtained 1 x 1012 photons/pulse at 98.5 nm for an input power of 2 MW at 295.6 nm. In the latter case the conversion efficiency is enhanced by a two-photon resonance via the CO A1II state. A simple model is outlined for third harmonic generation in a free jet, and the predictions of this model are tested against experiment.
