摘要:
Methods are disclosed for treating zircon-containing forming structures, e.g., zircon isopipes, with one or more treatment glass compositions in which defect-causing reactions between the zircon of the forming structure and molten glass are suppressed at the delivery temperature of the treatment glass. The treatment compositions can be used during start-up of a forming structure, between runs of the same production glass on a given forming structure, and/or when transitioning between runs of two production glasses on a given forming structure. The treatment compositions can be used with production glasses that are ion-exchangeable.

摘要:
An optically active fiber (30) is disclosed for making a fiber laser (18) or an amplifier (16). This double-clad structured active fiber (30) has a core (34), doped with an optically excitable ion having a three-level transition. The core (34) has a core refractive index and a core cross-sectional area. An inner cladding (32) surrounds the core (34). The inner cladding (32) has an inner cladding refractive index less than the core refractive index, an inner cladding cross-sectional area between 2 and 25 times greater than that of the core cross-sectional area, and an aspect ratio greater than 1.5:1. An outer cladding (36) surrounds the inner cladding (32) and has an outer cladding refractive index less than the inner cladding refractive index.

摘要:
The disclosed invention includes a method of making an optical fiber drawn from a multiple crucible. The method includes moving a first crucible of the multiple crucible relative to a second crucible of the multiple crucible. The invention also includes minimizing core and cladding diffusion. A tip of the first crucible is disposed axially above a tip of the second crucible by a preselected distance. The invention further includes the ability to alter a diameter of the core of the fiber. A differential pressure is applied to the first crucible. A positive differential pressure is applied to increase the core diameter. A negative differential pressure is applied to decrease the core diameter. Furthermore, the invention includes drawing the fiber under non-isothermal conditions; there is a thermal gradient of at least 10° C./m between the two tips.
