摘要:
In this article we present a study of a new class of optical fibers based on lead germanate glass. The maximum vibrational frequency of this glass is intermediate between silica and zirconium barium lanthanum aluminum fluoride glass, causing a beneficial change in nonradiative decay and therefore quantum efficiency for particular laser transitions. Fabrication of high‐strength, low‐loss fibers of this glass has been acheived by modification of the composition to produce optimal physical properties for fiber drawing, while retaining the useful vibrational properties of the original PbGeO2glass. Measurements of both the thermal and optical properties are described. The fibers produced are ideal for many applications in fiber devices.
