Abstract

Methods of preparation of single-crystal 4-N,N-dimethylamino-4′-N′-methyl stilbazolium tosylate (DAST) films with a thickness of several micrometers, designed for electro-optic modulation, have been analyzed. Thin-film single crystals have been obtained, the shape and absorption spectrum of which confirm their crystal structure of the “red” DAST crystal form. Homogeneous luminescence in the polarization-contrast regime indicates their single crystallinity and uniform orientation. These materials are designed for intracavity modulation of laser radiation.

用于腔内电光调制的薄膜非线性光学晶体

摘要

分析了制备用于电光调制的厚度为几微米的4- N，N-二甲基氨基-4'- N'-甲基苯乙烯基甲苯磺酸单结晶（DAST）薄膜的制备方法。已获得薄膜单晶，其形状和吸收光谱证实了其“红色” DAST晶型的晶体结构。偏振对比法中的均匀发光表明它们具有单一的结晶度和均匀的取向。这些材料设计用于腔内调制激光辐射。
