Paper Abstract

Single crystal (SC) yttrium aluminum garnet (YAG, Y3Al5O12) as a host material has the ability to be doped with high concentrations of Er3+ ions. We utilize this ability to grow a 50% Er3+ doped YAG SC fiber, which was inserted into a SC YAG tube. This rod-in-tube was used as a preform in our laser-heated pedestal growth (LHPG) apparatus to grow a fiber with a radial distribution of Er3+ ions. The work shows that there is a distribution of Er3+ ions from their fluorescence and two different techniques were used to measure the index of refraction.
