Abstract

Space-time resolved X-ray photograms of carbon (4671? thick with substrate) and gold (15μm in thickness) planar targets were obtained using a pinhole coupled to a soft X-ray streak camera. The planar targets were irradiated with laser (λ = 1.06 μm) pulses of about 100 ps duration from a LF-12 Nd: glass laser. The spectral response of the soft X-ray camera is defined to be 0.1-10 keV. Average plasma expansion velocities on the C and Au traget surface measured at a laser power density of about 1014 w/cm2 for were 5.l×107cm/s and 6.1×107 cm/s respectively.
