Mass-modulated plastic microballoons have been ablatively imploded by green (0.53 μm) laser light at an absorbed irradiance of 2×1013 W cm-2. Temporally growing spikes are seen on the outside surface of the target; evidence of the occurrence of mass redistribution indicates that the spikes are due to the Rayleigh–Taylor instability. A growth rate of 0.52±0.06 of classical has been inferred.

    The beam homogeneity and stored energy of discharge pumped KrF excimer amplifiers are critically dependent on the preionization level of the active medium and on the rise time of the electric excitation pulse.

    This work elucidates photoinduced two-dimensional (2D) gratings in dye-doped cholesteric liquid crystal films. The helical pitch is increased by green-beam-induced trans-cis isomerization and a concomitant thermal effect. Two-dimensional gratings appear when the green beam is turned off. Grating...
