ringdown 解釋
鈴流
  1. 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

    本文的主要內容有如下幾部分：第一部分：介紹了腔的歷史背景及其類型，以及一般f - p腔的原理和基本參數，分析了腔的精細度、光子壽命（衰蕩時間） 、品質因數等與腔損耗間的關系。
  2. 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

    實驗上建起一套由「超鏡」構成腔長為17 . 8mm的高精細度腔，並測得光在腔內的衰蕩信號，推算出腔的精細度約為20萬和損耗約為30ppm 。
