Scattered light diagnostics offer the attractive possibility of extracting detailed spatial information about the distribution of ions and electrons and associated plasma parameters in high-density plasmas that are relevant to inertial confinement fusion (ICF). Here, temporally integrated ultraviolet collective Thomson scattering measurements were performed with frequency-quadrupled Nd:YAG laser radiation on an underdense long-scale length aluminum plasma (n{sub c} {approximately} 10{sup 21} cm{sup {minus}3}, Z {approx} 7, T{sub e} {approx} T{sub i} {ge} 50 eV, L {ge} 100 {micro}m). The plasma was preformed by an Nd:YAG fundamental beam (1.06 {micro}m) with focusable intensities of 10{sup 11} W/cm{sup 2}. Color images of two-dimensional (2-D) spatially resolved (30 {micro}m) electron density and electron temperature were obtained. These are the shortest wavelength Thomson scattering measurements on a plasma to date.
