- The main parts of this thesis are as following : part 1 : it is briefly introduced the history and types of the f - p cavities , including the basic principle and parameters of the f - p cavity . moreover , the analysis is showed about the relations between the cavity finesse , ringdown time , quality factor and the losses
本文的主要内容有如下几部分：第一部分：介绍了腔的历史背景及其类型，以及一般f - p腔的原理和基本参数，分析了腔的精细度、光子寿命(衰荡时间) 、品质因数等与腔损耗间的关系。 - Part 2 : the background and principle of measuring the losses in the high - finesse cavity with the technique of ringdown are showed and the high - finesse cavity composed of super mirrors , with cavity length of 17 . 8mm is set up . by cavity - ringdown experiment , we can get the finesse about 2 105 and total losses of the high - finesse cavity about 30ppm
实验上建起一套由“超镜”构成腔长为17 . 8mm的高精细度腔，并测得光在腔内的衰荡信号，推算出腔的精细度约为20万和损耗约为30ppm 。
