Kinoform phase plates for focal plane irradiance profile control.
TL;DR: A versatile, rapidly convergent, iterative algorithm is presented for the construction of kinoform phase plates for tailoring the far-field intensity distribution of laser beams that contains more than 95% of the incident energy inside a desired region and is relatively insensitive to beam aberrations.
Proceedings ArticleDOI
NIF final optics system: frequency conversion and beam conditioning
Paul J. Wegner,Jerome M. Auerbach,Thomas A. Biesiada,Sham N. Dixit,Janice K. Lawson,Joseph A. Menapace,Thomas Gene Parham,David W. Swift,Pamela K. Whitman,Wade H. Williams +9 more
TL;DR: In this paper, the first forty-eight assemblies of the National Ignition Facility (NIF) were completed and the final optics design was described and selected results from first-article commissioning and performance tests are presented.
Proceedings ArticleDOI
Specification of optical components using the power spectral density function
Janice K. Lawson,C. Robert Wolfe,Kenneth R. Manes,John B. Trenholme,David M. Aikens,R. Edward English +5 more
TL;DR: In this paper, the power spectral density (PSD) function is used to characterize the wavefront of optical components, specifically, the use of the PSD function can be used to describe the intensity distribution at focus.
Proceedings ArticleDOI
Use of power spectral density (PSD) functions in specifying optics for the National Ignition Facility
TL;DR: In this paper, power spectral density (PSD) is used to characterize transmitted wavefront errors with spatial frequencies ranging from several centimeters to a few hundred nanometers, with amplitudes in the (lambda) /100 regime.
Proceedings ArticleDOI
NIF optical specifications: the importance of the RMS gradient
Janice K. Lawson,Jerome M. Auerbach,R. Edward English,Mark A. Henesian,J. T. Hunt,Richard A. Sacks,John B. Trenholme,Wade H. Williams,Milton J. Shoup,John H. Kelly,Christopher T. Cotton +10 more
TL;DR: In this paper, the authors studied the impact of long spatial wavelength phase errors on the performance of the National Ignition Facility (NIF) and concluded that the preferred metric for determining the impact is the rms phase gradient.
