利用非线性体全息技术，通过合理设计二维光学超晶格，实现了非线性过程中任意波前的整形。研究了非线性体全息中的非线性偏振波的概念。利用二维LiTaO 3晶体，在基波沿自发极化方向沿着传播的条件下，实现了不规则图形的全息成像，其结果与理论预测吻合较好。这封信不仅拓展了光学超晶格的应用领域，而且为波前整形技术提供了一种有效的方法。
Nonlinear volume holography is employed to realize arbitrary wave-front shaping during nonlinear processes with properly designed 2D optical superlattices. The concept of a nonlinear polarization wave in nonlinear volume holography is investigated. The holographic imaging of irregular patterns was performed using 2D LiTaO3 crystals with fundamental wave propagating along the spontaneous polarization direction, and the results agree well with the theoretical predictions. This Letter not only extends the application area of optical superlattices, but also offers an efficient method for wave-front shaping technology.
