Description

Optical resonators serve as excellent spatiotemporal filters and are widely used for suppressing laser phase noise and stabilizing laser frequency. They can also function as passive optical enhancement cavities, providing power gains of thousands to tens of thousands. High-power optical enhancement cavities hold promise for applications such as steady-state microbunching (SSMB) advanced light sources and gravitational wave detection. However, systematic studies on the phase noise characteristics of high-power optical enhancement cavities remain lacking. In this paper, based on a high-power optical enhancement cavity platform, we measure the phase noise of both the injected laser and the transmitted laser, and investigate the influence of key cavity parameters on the phase noise performance, thereby providing valuable references for the application of high-power optical enhancement cavities.
