Focusing lenses for the 20-beam fusion laser: SHIVA

Abstract

The SHIVA high energy laser facility now under construction at Lawrence Livermore Laboratory is a 20-arm, 1.06-µm Nd-glass laser system that can focus 20-30 TW of power nearly uniformly on a 300-1500-µm diam deuterium-tritium laser fusion pellet. The facility will be in operation in 1977 and should produce significant thermonuclear burn (fusion energy output = 1 % light energy input).
