Description

In high-power Fabry-Perot cavity applications, intracavity laser power can reach hundreds of kilowatts to the megawatt level, causing a non-negligible fraction of the energy to be deposited in mirror coatings and substrates. This absorption induces a range of thermal effects in the cavity, manifesting as instability of the stored power, cavity unlock, and excitation of higher-order mode resonances. This paper presents a Burst-Mode-based approach to suppress cavity thermal effects and thereby realize higher effective stored power. We further discuss the potential of Fabry–Perot cavities operating in burst mode to increase effective photon yield in Compton scattering experiments and their possible application to steady-state micro-bunching experiments.
