摘　　要：介绍了光学超晶格、准相位匹配原理和准周期光学超晶格等基本概念;简述了基于光学超晶格和固态激光技术的新型红绿蓝三基色激光器的设计方案,同时详细介绍了传统的Talbot效应在非线性光学领域的拓展,即光学超晶格中的二次谐波非线性Talbot效应.The basic concepts of optical superlattice, quasi phase matching theory and the quasi-periodical optical superlattice were briefly introduced. The design scheme for constructing a novel red-green-blue multiple-wavelength laser based on optical superlattice and solid-state laser techniques were also briefly introduced. In addition, the nonlinear second harmonic Talbot effect in optical superlattice, which is a nonlinear optical analogue to the traditional Talbot effect, was demonstrated.
