The influence of the reflection phaseshift and its dispersion on the optical performance of the short-cavity (SC) F-P interferometer was analyzed in details.
以此为基础，较为系统地研究了高反射镜面的反射相移及其色散对短腔长的F-P干涉仪光学性能的影响。

It is shown that the phase noise spectrum density shift periodicity with the length of external cavity and the peak value of power spectrum density varies considerably with the feedback coupling rate.
A novel way is suggested to narrow the bandwidth of a Fabry-Perot (FP) cavity through increasing the derivative of one round-trip phaseshift with respect to the frequency.
