Abstract

We report the influence of growth atmosphere and purity of starting material on the uv-visible transmission characteristics of sapphire fibers grown by the laser-heated pedestal growth method. Improved performance in the visible has been achieved by annealing the fibers to remove color center absorption associated with an impurity, likely a transition metal.
