Abstract

It is critical to know the free spectral range (FSR) of an etalon for telecommunication applications. In this paper, we have improved the Pound-Drever-Hall (PDH) based technique for measuring the FSR of an etalon by 2 orders of magnitude. This improved technique results 1 part in 10⁶ precision. To our knowledge this is the most precise measurement of FSR.
