Generation of Lyman-alpha radiation in phase-matched rare-gas mixtures.
When frequency tripling to Lyman-alpha in Kr, we find a Kerr-induced index mismatch per atom of gamma Kr = -5.6 X 10(-36) esu, which dominates the dispersion for power densities exceeding 4 X 10(12) W/cm2 . Results of phase matching Kr with Ar and Xe are presented. Dielectric breakdown provides a limitation that, when combined with a requirement of a 1-A bandwidth at Lyman-alpha, indicates that powers of a few kilowatts are achievable in a Kr-Ar phase-matched medium.
