    Abstract: Laser waveguides, methods and systems for forming a laser waveguide are provided. The waveguide includes an inner cladding layer surrounding a central axis and a glass core surrounding and located outside of the inner cladding layer. The glass core includes a laser-active material. The waveguide includes an outer cladding layer surrounding and located outside of the glass core. The inner cladding, outer cladding and/or core may surround a hollow central channel or bore and may be annular in shape.

    Abstract: A system and process for making a thin, soot particle or glass sheet is provided. The system includes a soot deposition plate having a deposition surface and a glass soot generating device spaced from the deposition surface along a first axis. The glass soot generating device is configured to generate glass soot particles and to deliver the glass soot particles through an outlet and on to the deposition surface in a layer having a thickness of less than 5 mm. At least one of the soot deposition plate and the glass soot generating device is movable to cause relative movement between the deposition surface of the soot deposition plate and the glass soot generating device. A thin soot or sintered soot sheet is also provided. The soot sheet has a variable surface topography that varies along at least two axes.
