Abstract: The design and experimental validation of a burst-mode optical cavity tailored for inverse Compton scattering X-ray sources is presented. The system is tailored for a room-temperature linear accelerator operating at 880 MHz and utilizes a common-path injection scheme for both locking and burst laser pulses to optimize stability and simplicity. We detail the cavity construction, the laser system, and the performance under two enhancement cavity finesse regimes (2000 and 7300), highlighting the sensitivity of cavity filling to carrier-envelope offset parameters. A theoretical model is developed to explain observed power dynamics and to guide optimization for high-energy storage. Our findings demonstrate reliable storage exceeding 300 mJ over 20 min, paving the way for compact, high-flux inverse Compton scattering X-ray sources.
