Abstract:
Laser driven inertial confinement fusion (ICF) has attracted much attention for its potential to solve the global energy crisis. As fused silica is an important functional ultraviolet (UV) element in the final optics assembly of ICF device, its laser-induced damage has become a key factor limiting the development of ICF output energy to a stronger and higher level. Therefore, the further increase of ICF output energy puts forward a significant application demand for the new UV components that have superior UV laser-induced damage resistance. In this paper, the research status of high-energy UV laser-induced damage of UV fluorophosphate glasses developed by Xi’an Institute of Optics and Precision Mechanics, CAS was reviewed, and the existing practical problems are analyzed. Finally, the development direction of UV fluorophosphate glasses with high laser-induced damage resistance is prospected.
