YAG CRYSTALS.

Abstract

A total of twelve yttrium aluminum garnet crystals have been grown and delivered in accordance with the schedule outlined in the Contract. These crystals are representative of the quality achievable with the presently utilized growth procedure. Furthermore, they are meant to provide a base line for comparison with crystals to be produced in the near future via improved techniques. Evaluation test results revealed that all of the crystals possessed a central core region regardless of growth orientation or Nd-dopant level. The size and shape of the core are the major determinants of quality in the as-grown crystals. The <111> growth direction was found to give the tightest core and therefore the highest optical quality crystals. (Author)
