    摘要： A method for forming a porous soot body that includes depositing soot on a release coating supported by a bait substrate. Characteristics of the release coating control the strength of attachment of the porous soot body to the bait substrate. Weak attachment of the porous soot body to the bait substrate facilitates separation of the porous soot body from the bait substrate without damaging the porous soot body. The release coating may be formed from a brittle material or a material that oxidizes or otherwise depletes during deposition of the soot that forms the porous soot body. The release coating may include carbon. The separated porous soot body may be consolidated to form a core cane or may function as a sleeve (porous cladding) in a cane-in-soot fiber preform manufacturing process.

    摘要： Double clad large mode area planar lasers or amplifiers comprising rare-earth or transition metal doped planar core regions are used to generate near-diffraction-limited optical beams of ultra-high power. The amplified light is guided in the core using different guiding mechanisms in two orthogonal axes inside the core. Waveguiding along a first long core axis is obtained substantially by gain-guiding or thermal lensing. Waveguiding along a second short core axis is obtained by index guiding. This is accomplished by surrounding the planar core region with regions of different refractive index. The long sides of the planar core region are surrounded with a depressed refractive index cladding region. The short sides of the planar core region are surrounded with a cladding region substantially index-matched to the core region. The whole structure is surrounded by an outer cladding region with a low refractive index to enable cladding pumping of the planar waveguide with high-power diode lasers. The rare-earth or transition metal doping level inside the planar core can be constant and can also vary substantially without negatively affecting the waveguiding properties. To avoid bend losses along the long axis of the planar waveguide, the planar core region and the planar waveguide are aligned parallel to each other and the planar waveguide is coiled with the long side of the planar waveguide mounted to a drum. The drum can also be used as a heat sink. A planar waveguide comprising a planar core region can be manufactured using conventional fiber fabrication methods.

Moreover, the invention relates to a procedure for manufacture of the quartz glass blank. A quartz glass blank of the described type should show little induced absorption and be optimized with respect to compaction and decompaction. The quartz glass blank according to the invention is characterized by the following properties: a glass structure essentially free of oxygen defect sites, an H2-content in the range of 0.1null1016 molecules/cm3 to 4.0null1016 molecules/cm3, an OH-content in the range of 125 wt-ppm to 450 wt-ppm, an SiH group-content of less than 5null1016 molecules/cm3, a refractive index inhomogeneity, nulln, of less than 2 ppm, and a stress birefringence of less than 2 nm/cm. In the use according to the invention, the quartz glass blank complies with dimensioning rules (2), (3), and (4) in terms of its minimal and maximal hydrogen contents and OH-content, CH2min, CH2max, and COH, respectively, with P being the pulse number and null being the energy density (in mJ/cm2): CH2minnullmolecules/cm3nullnull1null106 null2Pnullnull(2), CH2maxnullmolecules/cm3nullnull2null1018 nullnullnull(3), COHnullwt-ppmnullnull1,700nullnullnullmJ/cm2null0.4null50nullnull(4). The procedure according to the invention is characterized in that a mixed quartz glass is generated from a first and a second quartz glass by mixing the two quartz glasses in the course of a homogenization treatment.

    摘要： The invention includes inventive methods of treating a soot preform. One method includes heating a soot preform to a temperature of less than about 1000 null C. and exposing the preform to a substantially halide free reducing agent. Preferred reducing agents include carbon monoxide and sulfur dioxide. Another inventive method of treating the preform includes exposing the preform, in a furnace, to a substantially non-chlorine containing atmosphere comprising carbon monoxide. The preform is heated to a temperature of at least about 1000null C. Preferably this method is incorporated into the process for making an optical fiber. An additional method of treating the preform includes doping the preform with fluorine and exposing the fluorine doped preform to a substantially chlorine free atmosphere comprising at least carbon monoxide at a temperature of at least 1100null C., thereby reacting excess oxygen present in the furnace.

    摘要： A synthetic quartz glass substrate is prepared by annealing a synthetic quartz glass member having a higher hydroxyl content in a peripheral portion than in a central portion, machining off the peripheral portion of the member, slicing the member into a plate shaped substrate, chamfering and etching the substrate. The synthetic quartz glass substrate has a minimized birefringence and is suited for use as a photomask in photolithography.
