Abstract
Data from a pinhole camera and a transmission grating spectrograph
are used in multi-TW laser irradiance of thin metal films to assess
the maximum laser spot size and to show tenths of a percent
conversion of laser light to K-, L-, and M-band x rays. The
distribution of target debris, an operational issue for the
survivability of an unshielded parabola in a large laser system, is
revealed by x-ray fluorescence measurements of witness samples. At
the 25-J, 30-TW level, we find little evidence of damage to the f/3
parabola with an angle of incidence on target greater than
22
