LLE Review, Volume 69 1 The ultimate goal of the LLE uniformity program is to reduce the rms laser-irradiation nonuniformity to the 1%–2% level, which is required for cryogenic implosion experiments on OMEGA. The combination of distributed phase plates (DPP’s), two-dimensional (2-D) smoothing by spectral dispersion (SSD), polarization wedges, and beam overlap should be sufficient to reach this ...

The present objectives of the Drive Uniformity Program at the University of Rochester are (a) to determine the radiation and drive uniformity requirementsfordirectly driven targets, and(b)toachieve the required degree of uniformity with multiple beam irradiation of spherical targets using overlapping beams. This integrated program, which began almost two years ago, has made steady progress in m...

LLE Review, Volume 78 53 High laser-irradiation uniformity is an important requirement for successful direct-drive inertial confinement fusion (ICF). Direct-drive laser-irradiation uniformity is achieved on OMEGA for different ranges of spatial frequencies using smoothing by spectral dispersion (SSD), polarization smoothing with distributed polarization rotators (DPR’s), and multiple-beam overl...

LLE Review, Volume 75 151 A critical concern for Nd:glass fusion lasers such as OMEGA and the National Ignition Facility (NIF) is the uniformity of irradiation experienced by the fusion target. Uniform beams are generated by beam-smoothing schemes such as smoothing by spectral dispersion (SSD),1 which vary the instantaneous speckle pattern on target on time scales that are short compared with r...
