Abstract

High-finesse optical enhancement cavities (OECs) are powerful and versatile tools for various scientific investigations and measurements. They offer superior optical performance and have been widely researched and utilized. Finesse is a crucial parameter for OECs. It is essential to measure finesse accurately for OEC applications. Here, we outline the current development and potential applications of high-finesse OECs and introduce several finesse measurement methods. An OEC system with a length of 3.78 m is built and stable locking is achieved. Finally, the finesse is measured experimentally to be approximately 15,000 by the free spectral region (FSR) modulation method.
