High-Efficiency 800 nm Multi-Layer Dielectric Gratings for High Average Power Laser Systems( )

1 edition published in 2006 in English and held by 6 WorldCat member libraries worldwide

We report on the design, fabrication, and performance of a 1740 l/mm multilayer dielectric diffraction grating for use with 800 nm light. At an input angle of 8{sup o} from Littrow and a wavelength from 770 to 830 nm,>90% diffraction efficiency is achieved, with peak diffraction efficiency of>97% at 800nm. We will also comment on laser damage threshold and power-handling properties
Production of Gratings for High-Energy Petawatt-Class Lasers( )

1 edition published in 2006 in English and held by 6 WorldCat member libraries worldwide

At the time of this writing, we have manufactured and delivered more than 25 multilayer dielectric diffraction gratings from 470-800 mm in long aperture for pulse compression on Petawatt-class,1-micron laser systems being built at government and university facilities in the U.S and elsewhere. We present statistics of diffraction efficiency and its spatial uniformity, diffracted wavefront, and laser damage results on witness gratings. We also discuss yield, failure modes, and manufacturing improvements necessary to improve upon the current state of the art
Gratings for High-Energy Petawatt Lasers( )

1 edition published in 2005 in English and held by 6 WorldCat member libraries worldwide

To enable high-energy petawatt laser operation we have developed the processing methods and tooling that produced both the world's largest multilayer dielectric reflection grating and the world's highest laser damage resistant gratings. We have successfully delivered the first ever 80 cm aperture multilayer dielectric grating to LLNL's Titan Intense Short Pulse Laser Facility. We report on the design, fabrication and characterization of multilayer dielectric diffraction gratings

Ion Beam Deposition of (NbTa)2O5/SiO2 Multilayers for High-Efficiency Dielectric Gratings for High Average Power Laser Systems Operating at 800 nm Central Wavelength( )

1 edition published in 2006 in English and held by 5 WorldCat member libraries worldwide

The ion beam deposition of (NbTa)2O5 has been investigated for realizing high reflectance multilayer stacks of high damage threshold for applications in the engineering of dielectric gratings for use at 800 nm. Deposition conditions were optimized to yield fully oxidized films as determined from x-ray photoelectron spectroscopy (XPS). The film properties were also investigated using spectroscopic ellipsometry, and spectrophotometry to determine their refractive index and thickness respectively. Damage threshold testing was performed on single films using an amplified Ti:Sapphire laser producing a train of 170 ps pulses at a wavelength of 800 nm with an average energy of 100 mJ. The laser output was focused at the surface of the samples via a 0.5 m focal length lens to generate fluences ranging from 0 to 9 J/cm{sup 2}. At the optimum deposition conditions for highest optical quality and damage threshold, high reflector stacks of (NbTa){sub 2}O{sub 5}/SiO2 were fabricated. These stacks were employed to fabricate dielectric gratings with 1740 l/mm for use with 800 nm light. At an input angle of 8{sup o} from Littrow and a wavelength from 770 to 830 nm,>90% diffraction efficiency is achieved, with peak diffraction efficiency of>97%. The demonstration of dielectric gratings at 800 nm is opening the pathway to significantly increase the power handling capabilities of grating compressors for picosecond and femtosecond chirped pulse amplifications systems
Computational intelligence and its applications : evolutionary computation, fuzzy logic, neural network and support vector machine techniques( )

1 edition published in 2012 in English and held by 3 WorldCat member libraries worldwide

This book focuses on computational intelligence techniques and their applications - fast-growing and promising research topics that have drawn a great deal of attention from researchers over the years. It brings together many different aspects of the current research on intelligence technologies such as neural networks, support vector machines, fuzzy logic and evolutionary computation, and covers a wide range of applications from pattern recognition and system modeling, to intelligent control problems and biomedical applications. Fundamental concepts and essential analysis of various computational techniques are presented to offer a systematic and effective tool for better treatment of different applications, and simulation and experimental results are included to illustrate the design procedure and the effectiveness of the approaches

Conditional logic in expert systems( Book )

2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide

This paper first develops an extension of the Negoita-Ralescu Representation Theorem for fuzzy sets in terms of flou sets relative to operators and partitionings. It then reviews in some detail both the random set/random variable basis for fuzzy sets, as well as the foundation of conditional event algebras. Both of these areas are tied together, first in the form of conditional event indicator functions, and then through the development of conditioning fuzzy sets. Specifically, it is shown that the structure of conditional event algebra as proposed here drives the structure for fuzzy conditioning, resulting in conditional fuzzy sets being necessarily of a simple form relative to their membership functions to a given marginal. It is seen that with this approach, a full calculus of operations, extending that of ordinary conditional events, is obtained
