Abstract: PURPOSE: To obtain glass having a uniform film thickness and uniform physical properties by hydrolyzing metallic alcoholate contg. silicon alkoxide as a principal component in the presence of water or an org. solvent after adding a viscosity regulator so as to regulate the viscosity of the resulting soln. to the desired value.
CONSTITUTION: To silicon alkoxide is added metallic alcoholate of Ti, Zr or the like, and to this added alcoholate are added a viscosity regulator having a superior thickening effect such as aqueous cellulose ether and water or an org. solvent such as methanol. By agitating them, the alcoholate is hydrolyzed to prepare a viscous soln. with about 5W30cps viscosity. By this viscosity regulation molded glass products having various shapes such as separate films, fibers, substrate coating and lump glass can be obtd.

Abstract: An active optical fibre, including: a core; an inner cladding substantially surrounding the core, whereby the core and the inner cladding form an area configured to propagate pump radiation; an outer cladding comprised of at least a third material with at least a third refractive index substantially surrounding the inner cladding, the third refractive index being smaller than the second refractive index, whereby the outer cladding confines pump radiation to the core and the inner cladding; and a coating comprised of a thermally conductive material substantially surrounding the outer cladding, wherein the inner cladding is configured to reduce impact of spatial hole-burning on absorption of the pump radiation as the pump radiation propagates through the active optical fibre, and wherein the thermally conductive material of the coating supports a reduced temperature increase between the area and an outer surface of the coating.
