摘要
利用准相位匹配技术,通过人为地在非线性晶体上制备出非线性系数的周期结构,来满足相位匹配条件,可以提高频率转换效率与扩大非线性晶体的应用波段范围,这是近年来光学非线性研究的重要发展方向.利用铌酸锂晶体畴工程制作极化周期结构,以实现准相位匹配技术是最为突出的例子.本文详细介绍了这一技术手段以及应用发展趋势.
Abstract
Quasi-phase-matching is a technique for phase matching nonlinear optical interactions which the nonlinear coefficient is modulated spatially at regular intervals using a structural periodically built into the nonlinear medium. Using this technique, higher conversion efficiency can be obtained and nonlinear interactions over the entire transmission band of the material can be utilized. In particular, the periodically poled domain structure in LiNbO3 has become the most important sample, which was fabricated by domain engineering. The development and trend of quasi-phase-matching technique are introduced in detail.
