Properties of fused silica ceramics

Refractories, 1968
We investigated the relationship between thermal conductivity, specific heat, and temperature conductivity of fused silica ceramics with a true porosity of 1.5–28%, and temperature. Above 500°C we detected a sharp deviation in the thermal conductivity of fused silica ceramics from this factor recorded for fused silica. The deviation is explained by the

Fused-silica-clad Cr:YAG fiber

CLEO/Pacific Rim 2003. The 5th Pacific Rim Conference on Lasers and Electro-Optics (IEEE Cat. No.03TH8671), 2004
A low-propagation-loss (< 0.1 dB/cm) fused-silica-clad Cr:YAG fiber is demonstrated and investigated. The simulation shows that more than 0 dBm of amplified spontaneous emission could be generated with a 2-W pump and an 8-/spl mu/m core.

Intrinsic defects in fused silica

Journal of Non-Crystalline Solids, 1985
Abstract It is argued that twofold coordinated silicon defects (Si 2 0 ) instead of oxygen vacancies could be the lowest energy silicon-excess defects in oxygen deficient fused silica.

CO2 laser welding fused silica

ICALEO 2005: 24th International Congress on Laser Materials Processing and Laser Microfabrication, 2005
The feasibility of laser welding of fused silica (aka quartz) has been demonstrated recently by others[1,2]. An application requiring hermetic sealing of a thin, pressure-bearing quartz diaphragm to a thicker frame led us to explore this technique.

Fused-silica monolithic total-internal-reflection resonator

Optics Letters, 1992
We have characterized a miniature fused-silica monolithic optical ring resonator in which the Gaussian mode is confined by total internal reflection. Laser light is coupled into and out of the resonator by frustrating one of the total internal reflections by means of a prism.

The strength of fused silica

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1967
Silica fibres and flame polished rods having strengths around 600 Kg/mm 2 were prepared and the preparation conditions studied. The effects on fibre strengths of atmospheric and temperature changes, and of variations in rate of stressing and previous heat treatment, were extensively investigated.

Femtosecond Laser Nanomachining Applications in Fused Silica

2007 Conference on Lasers and Electro-Optics (CLEO), 2007
Focused femtosecond laser light can produce beautifully arrayed self-organized nanocracks inside fused silica. These nanocracks provide a unique capability for nanomachining micro- and nanofluidic channels, nanoporous capillaries and rewritable data storage elements.

Improvement in polishing of fused-silica parts

Applied Optics, 1991
High-power laser optics can require high-quality polished surfaces for damage resistance. Fabrication efficiency for producing quality surfaces becomes an important cost consideration. Our systematic study of fused-silica polishing conditions has led to the discovery that enhanced removal efficiency and higher quality optical surfaces can be achieved ...
