    Abstract: The laser-heated pedestal growth (LHPG) of chromium-doped yttrium aluminum garnet (Cr:YAG) single-crystal fibers in <111> direction was investigated via a two-dimensional (2D) simulation verified by observations on the interface shapes. The normalized radial dopant profiles at the growth front are consistent with that of the grown crystal fibers in ex-situ measurements. The concentration level and distribution with the corresponding fluid flow and heat transfer were reported to visualize the phenomena that cannot be observed easily. It is viable to adjust the air/melt interface, the mass-flow distribution, and especially the growth front to acquire a crystal fiber with a desirable radial dopant distribution.
