Abstract
Oriented single crystals of the laser host material LiYF4, doped with either Er3+ or Nd3+, have been grown by seeded vertical gradient freez ing (VGF). Successful seeding, requiring a rather high amount of exces s LiF in the melt, allowed or the production of crystals of high optic al quality. In the case of neodymium doping, the dopant distribution c ould be related to different convective flow patterns present at diffe rent stages of growth.
