Abstract
Single, acentric, hexagonal, beryllium borate crystals having the formula Sr2Be2B2O7 and of a size sufficient for use in a variety of laser and non-optical applications are formed by a hydrothermal method. Alternate structures are formed by partially substituting the strontium ion with at least one other divalent metal ion.
