Description
Optical enhancement cavities represent a technical approach for achieving high average power lasers, demonstrating significant potential in both fundamental and applied research. To realize the goal of megawatt-level intracavity power, an experimental platform for high-power continuous-wave optical enhancement cavity has been established. Current optimizations to the experimental system include: upgrading laboratory cleanliness to Class 100 standards; enhancing cavity vacuum levels; employing low-loss cavity mirrors with mounts suppressing thermal deformation; refining optical cavity design and optical path alignment techniques; utilizing D-shaped mirrors to mitigate thermal-induced mode instability; and optimizing feedback control loops to improve system stability and robustness. In the optimized experimental research, stable cavity operation at the hour level was achieved with an incident laser power of 25.8W and an intracavity power of 224kW, yielding an effective gain of 8682. Ultimately, we achieved a maximum internal circulating power of 876kW with an incident laser power of 101W. The cavit
