Features of the etching of an yttrium-lithium fluoride crystal in HNO3 solutions

摘要

This paper discusses the etching kinetics of a LiYF4:Nd3+ crystal in HNO3 Solutions at various etchant concentrations and temperatures. The etching rates of the crystal along the three principal crystallographic directions are determined. The resulting data make it possible to optimize and control the etching process, which increases the mechanical strength and thermal stability of LiYF4:Nd3+ crystals.
