1. A method of making a multi-composition fiber, the method comprising:
providing a precursor laden environment;
forming a fiber in the precursor laden environment using laser heating; and
wherein the precursor laden environment comprises a primary precursor material and an elemental precursor material, and wherein the formed fiber comprises a primary fiber material and an elemental additive material, the elemental additive material having too large an atom size to fit within a single crystalline domain within a crystalline structure of the fiber, and being deposited on grain boundaries between adjacent crystalline domains of the primary fiber material to present an energy barrier to atomic diffusion through the grain boundaries, and to increase creep resistance by slowing down grain growth between the adjacent crystalline domains of the primary fiber material.
