Background technology
(Nonlinear Optics is a frontier of contemporary optics NLO) to nonlinear optics, is the research response of material and science of the nonlinear relationship that field intensity presents under the high light effect.In numerous non-linear optical effects, frequency-doubled effect (SHG) be the most noticeable also be the non-linear effect of studying at most.Optical material with non-linear effect is in modern science and technology, in particularly some civilian and military high-tech areas, for example photoelectricity communication, optical information storage, unicircuit, photoswitch, light slicer, color laser printing, blinding laser weapons, the ocean locating fish etc. all have a series of important application.
Studies show that borate compound compares the non-centrosymmetrical structure of the easier formation of compound of other type, but not the structure of the heart is the precondition that produces non-linear optical effect.Therefore, for a long time, the borate crystal of nonlinear optics is people's a research focus always.The nonlinear optics borate crystal of practical application comprises LiB at present
