Abstract
A nonlinear optical crystal having a chemical formula of YiLajAlkB16O48, where 2.8≦i≦3.2, 0.8≦j≦1.2, i and j sum to about four, and k is about 12 is provided. The nonlinear optical crystal is useful for nonlinear optical applications including frequency conversion. Nonlinear optical crystals in a specific embodiment are characterized by UV blocking materials (e.g., some transition metals and lanthanides) at concentrations of less than 1,000 parts per million, providing high transmittance over portions of the UV spectrum (e.g., 175-360 nm).
Claims13
A method of growing one or more nonlinear crystals of a composition, the method comprising:
- providing a set of constituent components of the composition including an R source, a lanthanum source, a boron source, and an aluminum source, where R is selected from an elemental group consisting of yttrium and lutetium;
- mixing the set of constituent components of the composition to form a component mixture;
- heating the component mixture to a predetermined temperature, thereby forming a resultant melt;
- cooling the resultant melt;
- and
- forming the one or more nonlinear crystals of the composition as a precipitate from the resultant melt, wherein the one or more nonlinear crystals have a chemical formula of RiLajAlkB16O48, where 2.8≦i≦3.2, 0.8≦j≦1.2, i and j sum to about four, and k is about 12.
