Abstract

Summary form only given. We studied high harmonic generation in jets of atomic gases Ar and Xe as well as diatomic molecular gases H₂, D₂, N₂, and O₂ using a linearly polarized picosecond dye laser (594nm) and a linearly polarized subpicosecond Ti:sapphire/Nd:glass laser (1053nm). The harmonic conversion efficiencies are compared by choosing different gas pairs as a function of three parameters: (1) field-free ionization potential (2) mass and (3) static average polarizability
