TL;DR: Results demonstrate that the NIF will meet its laser performance design criteria, and that theNIF can simultaneously meet the temporal pulse shaping, focal-spot conditioning, and peak power requirements for two candidate indirect drive ignition designs.
Journal ArticleDOI
Raman pulse compression of excimer lasers for application to laser fusion
TL;DR: In this paper, the backward Raman amplifier is shown to be a promising candidate for this application and gain, saturation, and limits to amplifier performance are described, and design tradeoffs and possible techniques for further improving the performance of such amplifiers are discussed.
Journal ArticleDOI
ORION: Clearing near-Earth space debris using a 20-kW, 530-nm, Earth-based, repetitively pulsed laser
Claude R. Phipps,G. Albrecht,Herbert W. Friedman,Donald T. Gavel,E.V. George,John R. Murray,C. Ho,W. Priedhorsky,M. M. Michaelis,James P. Reilly +9 more
TL;DR: In this paper, the authors used a ground-based laser system and active beam phase error correcting beam director to provide the impulse, together with a new, computer-intensive, very high-resolution optical detection system to locate objects as small as 1 cm at 500 km range.
Journal ArticleDOI
Performance of a prototype for a large-aperture multipass Nd:glass laser for inertial confinement fusion
B. M. Van Wonterghem,John R. Murray,John H. Campbell,D. R. Speck,Charles E. Barker,I.C. Smith,Donald F. Browning,W. Behrendt +7 more
TL;DR: The Beamlet is a single-beam prototype of future multibeam megajoule-class Nd:glass laser drivers for inertial confinement fusion that uses a multipass main amplifier, adaptive optics, and efficient, high-fluence frequency conversion to the third harmonic.
Proceedings Article
Experimental observation and suppression of transverse stimulated Brillouin scattering in large optical components
John R. Murray,J. Ray Smith,R. B. Ehrlich,Demos T. Kyrazis,Calvin E. Thompson,Timothy L. Weiland,Russell Wilcox +6 more
TL;DR: In this paper, a transverse stimulated Brillouin scattering (SBS) was observed in fused-silica optical components using 2.4-nsec pulses at 350 nm.
