OSTI ID:6503995
Gold planar targets have been irradiated with nanosecond, 1.06 ..mu..m laser pulses focused to intensities of 3 x 10/sup 14/ and 3 x 10/sup 15/ W/cm/sup 2/. Two target orientations coupled with multiple diagnostic lines-of-sight provided angle dependent x-ray emission data at these two laser conditions. Time resolved filtered x-ray diodes, crystal spectrographs and an absorption edge x-ray spectrometer observed the spectral range between 0.2 and 30.0 keV. Approximate integrals of the measured x-ray distributions subtracted from associated laser absorption data imply laser-plasma energy coupling efficiencies.
