摘要: 激光作为20世纪最重大的科技发明之一,不但广泛地应用于科技领域的最前沿,还对人们的日常生活及工业生产产生了深远的影响,全球与激光相关的产业价值已经超过了千万亿美元的年产值。光学谐振腔是光波在其中来回反射从而提供光能反馈的空腔。由于激光谐振腔在工作过程中会产生热效应,会对谐振腔的稳定性造成一定的影响。本文正是对谐振腔的稳定性和热效应进行了深入的分析与研究。
本文首先对光学谐振腔进行了概述,然后阐述了光学谐振腔类型及其稳定性基本理论、工作介质热效应的理论知识及热效应的危害等。在本文第三章,以倍频声光调Q激光器为对象,利用数学软件MATLAB编写程序进行谐振腔稳定性计算,根据稳定性结果,得到谐振腔几何参数范围,以确保谐振腔能够工作于稳定区。最后对本次设计进行了总结和展望。

Research on designing laser resonant cavity and its thermal stability
Abstract: Laser, as one of the most significant technological invention in twentieth century, not only widely used in the field of science and technology, but also had a profound impact on people's daily life and industrial production. The global output value of laser-related industry has exceeded a million billion dollars every year. Optical resonant cavity in which light reflects back and forth can provide energy feedback. As the laser cavity in the work process will produce thermal effects, cavity stability would have been affected. In this article, resonant cavity stability and thermal effect are analyzed and studied deeply.
This paper first summarizes the optical resonant cavity, and then describes the optical resonator type and the basic theory of stability, the theory and knowledge of working medium thermal effects and the hazards of thermal effects etc. In the third chapter, aimed at the frequency doubling and acousto-optic Q-switched laser, mathematical software MATLAB was used, then I write a program to calculate the resonant cavity stability. According to the results of stability, the resonant cavity geometry parameters were got, to ensure that the resonant cavity can work in the stable region. In the end I make a summary of the graduation design and an outlook.
