Review 80


LLE Review 80 covers a broad range of research topics, beginning with two theoretical analysis articles. The first feature article explains how laser nonuniformity can generate mass perturbations through ``laser imprint." Modulated laser illumination is shown to impact the predicted stability of velocity and acceleration of material during the early portion of the irradiation; thermal smoothing and mass ablation are shown to mitigate the perturbations. Simulated NIF direct-drive cryogenic designs with 1-THz SSD remain intact during the implosion. The second feature article distills self-focused filament stability in laser-formed plasmas to a tractable prediction of stability over a variety of size and shape filaments. This issue also presents articles on the following topics:

  • Broadband SSD implementation on OMEGA: architecture and integration issues
  • Temporal pulse shape's effect on laser imprinting and beam smoothing: experiments and simulations
  • Laser regenerative amplifier signal-to-noise experiments and modeling, covering sources of noise and system optimization
  • Optical fabrication developments that highlight the extension of magnetorheological fluid (MRF) techniques to crystalline optical materials.
