Abstract:
Comparative analysis of structure and chemical properties of mechanically polished surfaces of LiB3O5, β-BaB2O4, and CsB3O5 nonlinear crystals have been conducted by use of RHEED and XPS methods. It is shown that usually optical surfaces of these crystals are covered with a 5-nm and thicker layer of amorphous material. This modified layer can be removed by mechano-chemical aftertreatment without loss of optical quality, which increases chemical stability of the surface in air.
