The principal work in this paper is to investigate the third - order nonlinear optical properties of three new organometallic complexes with z - scan technique, and study the molecule structural vibration of these complexes. in order to further understand their nonlinear optical characters there are six chapters in this paper, which can be divided into three sections : in the first section, i. e. chapter one, the current status of the development and practical applications of nonlinear optics are introduced briefly the third - order nonlinear optical effect is introduced particularly
本文的工作主要是利用單光束z掃描技術研究了三種新型金屬有機化合物的三階非線性光學特性，並且利用拉曼光譜技術探索了這些化合物的結構振動信息，試圖從結構方面更深入的了解其非線性光學性質。論文共分六章，其主要內容概括為三個部分：第一部分，即論文的第一章，簡單介紹了非線性光學發展的現狀以及非線性光學的現實應用和意義，著重介紹三階非線性光學效應，用z掃描方法測量三階非線性光學系數的方法和理論。
