We report high-power vacuum-ultraviolet (vuv) generation at the Lyman- α wavelength of 121.6nm , using a simple experimental system. vuv radiation is produced through two-photon-resonant difference-frequency mixing with a tunable ArF excimer laser and a Nd:YAG-pumped dye laser. Using phase-matched mixtures of Kr and Ar at a total pressure of 650 mbar, we produced 7-µJ energies at Lyman- α in approximately 5ns (1.3kW) , as measured directly with a pyroelectric energy probe. Measurements indicate that higher powers are possible with system optimization. A tuning range of 0.1nm was achieved for a fixed gas mole fraction at a total pressure of 650 mbar. Qualitative agreement is found between measured tuning profiles and theoretical predictions.

  13. To achieve agreement with Ref. 13 and the figures of Ref. 11, we use only positive k values in Eq. 3 of Ref. 11. We do use a negative sign for the parameterized distance e for the difference (dye) wavelength.
