Abstract

The time dependence of the spatial coherence of the combined spectral lines at 23.2 and 23.6 nm from the Ge XXIII collisionally pumped soft-x-ray laser with a double-slab target is examined within a single nanosecond pulse by use of Young’s interference fringes and a streak camera. High source intensity is linked with low spatial coherence and vice versa. Calculations of the source intensity, size, and position have also been made; these calculations refer to a single-slab source. Comparison between the observed and calculated intensities, and of the source sizes both calculated and derived from the Young’s fringes by interpretation with a Gaussian model of source emission, show good agreement in general trends.
