| Popis: |
High brightness tunable coherent extreme ultraviolet (XUV) radiation at 79 nm with a peak power of ∼200 mW has been generated in H 2 gas by sum frequency mixing of two quanta from a high spectral brightness ArF* (193 nm) source with one quantum from a tunable dye laser (∼436 nm). Spectroscopic application of this radiation has been demonstrated by observation of a broad (∼160 cm-1) autoionizing structure in Ar and narrow (∼2 cm-1) autoionizing features in D 2 . An analysis is given which identifies the dominant molecular states involved in the nonlinear susceptibility of the medium (H 2 ). The frequency independent tuning behavior of the 79 nm output power observed over ∼300 cm-1is related to the molecular structure and response of the nonlinear medium in the intense optical field. |
