Abstract
A theoretical model of single-crystal fibre growth by laser-heated miniature pedestal growth has been developed to account for the transfer of dopant from the source rod to the growing fibre. This model predicts the time evolution of the melt dopant concentration when the source rod dopant concentration is axially non-uniform. From this the axial distribution of dopant in the final grown fibre may be predicted. This model has been experimentally confirmed and an estimate of the evaporation time constant of Ti in the growth of Ti:Al 2O 3 fibres made.
