Abstract: Disclosed is an optical fiber formed from a preform that includes a clad material and a core material. The clad material includes an oxide glass and the core material includes as a primary component a semiconductor material that melts at a temperature below where the cladding glass draws into fiber. In addition, the core material includes a scavenger for oxide precipitates that can precipitate into the core from the adjacent clad material during the fiber formation process. During formation, the scavenger reduces oxide precipitate to form the core primary component, or a phase compatible with it, and volatile products. The volatile products evolve out of the system. The primary material of the core can melt during the fiber formation process and crystallize upon cooling leaving the formed optical fiber with a crystalline core and little or no impurities due to precipitation of oxide into the core.

Abstract: Disclosed are heterogeneous crystals for use in a laser cavity and methods of forming the crystals. A crystal can be a monolithic crystal containing regions that are based upon the same host material but differ from one another according to some material feature such that they can perform various functions related to lasing. Disclosed methods include hydrothermal growth techniques for the growth of differing epitaxial layers on a host. A host material can be doped in one region with a suitable active lasing ion and can be formed with another region that is undoped and can act as an endcap, a waveguide cladding layer, or a substrate to provide strength and/or contact to a heat sink. Regions can be formed with controlled thickness in conjunction. Following formation, a heterogeneous crystal can be cut, polished and coated with mirror films at each end for use in a laser cavity.
