    摘要： A method of processing an optical fiber includes drawing the optical fiber from a heated glass source, reheating the optical fiber, and cooling the optical fiber under vacuum at a cooling rate less than the cooling rate of the optical fiber in air at 25° C. and 1 atm. Cooling the optical fiber under vacuum is conducted after reheating the optical fiber. Cooling the optical fiber under vacuum reduces the rate of heat transfer from the optical fiber, which may enable further relaxation of the glass and reduction in the fictive temperature of the optical fiber. A system for processing an optical fiber includes a furnace containing a fiber preform, a first positioner, a reheating device, and a treatment device downstream of the reheating device, the treatment device operable to cool the optical fiber under vacuum to reduce the rate of heat transfer from the optical fiber.

    摘要： A laminated glass article has a first layer having a first ion exchange diffusivity, D0, and a second layer adjacent to the first layer and having a second ion exchange diffusivity, D1. D0/D1 is from about 1.2 to about 10, or D0/D1 is from about 0.05 to about 0.95. A method for manufacturing the laminated glass article includes forming a first layer having a first ion exchange diffusivity, D0, and forming a second layer adjacent to the first layer and having a second ion exchange diffusivity, D1. The laminated glass article can be strengthened by an ion exchange process to form a strengthened laminated glass article having a compressive stress layer with a depth of layer from about 8 μm to about 100 μm.
