Preparation of Rare Earth Doped Laser Materials.
Abstract
This report describes the preparation of specific host materials doped with either Ce(3+) or Pr(3+). The materials were prepared by either a solid phase sintering, crystallization from a high temperature flux, or direct growth by the Czochralski method from a melt. Both the amount of dopant and particularly the valence state of cerium were important variables in attempting to control fluorescence. Samples were prepared for both spectral investigations and possible laser schemes in the blue-green region. Growth atmospheres and conditions were adjusted to yield the maximum amount of Ce(3+) in single crystals. YAG:Ce(3+) and YAlO3:Pr were prepared in fabricated forms of disks, rectangular rods or cylindrical rods. These crystals were then examined at other laboratories. (Author)
