铌酸钾锂晶体的非线性光学性能及其倍频特性分析

ANALYSIS OF THE NONLINEAR OPTICAL PROPERTIES AND FREQUENCYDOUBLING CHARACTERISTICS OF POTASSIUM LITHIUM NIOBATE CRYSTALS

简要综述了ＫＬＮ晶体的非线性光学性能，并根据非线性光学理论分析了ＫＬＮ晶体的倍频特性。结合ＫＬＮ晶体在蓝光倍频中的应用，讨论了当前ＫＬＮ晶体生长和性能研究中所要解决的几个关键问题。

The nonlinear optical properties of KLN crystals are briefly reviewed,and the frequencydoubling characteristics of KLN crystals are analysed according to the nonlinear optical theory.Finally,several key problems in the current studies of KLN crystal growth and properties are discussed in the light of applications of the KLN crystals in the frequencydoubling for blue laser light generation.
