    Abstract

    With the ongoing progress of pulse laser storage technology, a compact X-ray source based on laser-Compton scattering, with sufficient photon flux for practical use, is soon to be realized. The super-cavity is one of the most feasible sources for the production of both high-average-power and high-peak-power laser pulses. Our group has been developing a continuous pulse storage and quasi-continuous interaction scheme with a multi-bunch electron linac. We have demonstrated a burst storage technique that enhances the laser pulse energy synchronized with the electron bunch train by using a quasi-continuous-wave laser amplifier. This laser pulse storage technique has achieved an average power of 2.45 kW and a pulse energy of 112 μJ at the interaction timing in a super-cavity. In this paper, we describe the principle and recent progress of laser pulse storage in an optical super-cavity.
