Description

A kind of nonlinear optical crystal diethylenetriamine cadmium aluminum hexaborate and its preparation and application technical field The invention relates to a nonlinear optical material diethylenetriamine cadmium aluminum hexaborate (chemical formula: [Cd(dien) 2 ][AlB 6 o 11 (OH)]) preparation and application. Background technique Nonlinear optics (Nonlinear Optics, NLO) is a new field of modern optics. It is a science that studies the nonlinear relationship between the response of matter and the field strength under the action of strong light. Among the numerous nonlinear optical effects, the frequency doubling effect (SHG) is the most noticeable and the most studied nonlinear effect. Optical materials with nonlinear effects are used in modern science and technology, especially in several civilian and military high-tech fields, such as optoelectronic communications, optical information storage, integrated circuits, optical switches, optical limiters, color laser pr...
