环形腔扫描干涉仪及其模匹配的研究

Investigation of ring resonator scanning interferometer and its mode match

介绍了用环形谐振腔制做而成的新型扫描干涉仪，它的设计原理是基于谐振腔之间的模匹配理论。用它来测定激光模式时不需要加隔离器。文中对于激光腔和环形谐振腔的模失配和失调问题也进行了讨论。这一装置有很好的应用前景。

We present a new scanning interferometer made by a ring resonator.The system design is based on mode coupling theory for matching two resonators.It is not necessary to have a isolator for measuring the operating mode of a laser.We also discusses the error of misalignment and mismatch caused by the laser cavity and ring resonator.The scanning interferometer will have wide application prospect.
