This edition of the LLE Review contains articles on target interaction experiments on OMEGA and GDL, characterization of symmetry on OMEGA, frequency-conversion technology, advances in target characterization and picosecond research, and NLUF experiments performed on OMEGA during the first quarter of fiscal year 1983 (October-December 1982). The following are some of the highlights of the work described in this issue: (1) a theoretical analysis of illumination uniformity on spherical targets has been developed; (2) an extensive series of thermal-transport experiments at 1.05 ..mu..m on OMEGA is reported; (3) spherical targets on OMEGA have been photographed in their harmonic emissions at 2..omega../sub 0/, 3..omega../sub 0//2, and 5..omega../sub 0//2; (4) measurements of the continuum x-ray spectra produced by ir- and uv-generated laser plasmas on GDL are reported; (5) a single, monolithic, frequency-conversion cell has been designed, and will be used for the conversion of the first six beams of OMEGA to the uv; (6) an improved interferometric technique for the characterization of nonconcentricity in transparent inertial-fusion targets has been developed; (7) an improvement in an LLE-developed system for time-resolving short electrical signals has led to the generation and measurement of a step-function electrical signal with a rise time of 850 fs; and (8) shifts and widths of hydrogenic ion lines emitted by the dense plasmas generated on OMEGA have been observed in an NLUF experiment.
