Abstract

The objective of this chapter is to summarize the advantages in sol-gel processing of net silica optics. The advantages discussed include: homogeneity, purity, coefficient of thennal expansion, optical transmission, as-cast shapes and surface features, and the unique properties of porous silica matrices used for doping applications and laser-enhanced densification.

The potential disadvantages of sol-gel processing are inherent to size scaleup. They can be overcome by well-defined processing steps including: control of gel texture through hydrolysis, condensation and aging reactions, control of drying, elimination of casting defects, and precise atmosphere control.
