The spectral and spatial characteristics of X-ray emission (5-200?) along or off the axis of the plasma column, produced by 1.06 μm laser beam irradiating luminum flat target in line focused configurations with an average power density 2×1012W/cm2, are studied by using a pinhole transmission grating spectrograph (PTGS). Problems for the plasma as an X-ray-laser gain medium are also discussed.
