为探索有机非线性光学材料在光限幅方面的应用,本论文合成了四种烷氧基取代的金属酞菁化合物,并利用元素分析、红外光谱、核磁共振氢谱等方法,验证了化合物的分子结构。分别将四种化合物掺入聚合物单体(MMA)中,制备出具有非线性光学性质的金属酞菁/聚甲基丙烯酸甲酯(PMMA)复合材料。 用YAG倍频调Q脉冲激光器测试了复合材料的非线性反饱和吸收性质,发现材料具有明显的光限幅效应。同时,讨论了影响材料反饱和吸收性质和光限幅作用的主要因素,探讨了复合材料在光限幅上的可行性及不足之处。对于多波段,高光密度,高透过率的光限幅材料的研制,本论文做出了有益的尝试。

摘要:创新型社会提倡教学方法的创新,同时也必须有相应的教学评价与之同步。所谓新型评价,即要求在评价内容和评价方法上都有创新。教学评价是一门艺术,它需要人们不断地充实与完善。但无论何时何地,我们的教学评价都要坚持“以学生为本,以创新为源”的教学理念。  关键词:多元化;多样化;艺术性  中图分类号:G633.3 文献标识码:A 文章编号:1992-7711(2017)01-0074  在教学中,我们
