Third-harmonic generation in a pulsed supersonic jet of xenon.
Third-harmonic generation to 1182 A is reported in a pulsed supersonic jet of xenon. Using a valve equipped with a 1-mm-diameter nozzle and for an incident power of 18 MW at 3547 A, I have obtained a peak power of 260 W in a 2.9-nsec pulse, corresponding to 4.7 x 10(11) photons per pulse and an average power of 7.5 microW at 1182 A. The measured conversion efficiency is comparable with that in a bulk-gas cell.
