Nonlinear optical crystals and their manufacture and use

摘要: Described are nonlinear optical (NLO) crystals, including aluminum-borate NLO that have low concentrations of contaminants adversely affect the crystal's properties, such as compounds contain transition-metal elements and/or lanthanides, other than yttrium, lanthanum, and lutetium. Some crystals with these capable second harmonic generation at very short wavelengths. Also described embodiments a method for making crystals. involve growing single crystal, an from mixture containing solvent is substantially free harmful contaminants. The can be used, example, in laser devices.
