TL;DR: In this article, the authors demonstrate that the ionization-limited attainable intracavity peak intensity increases with decreasing pulse duration, which can be used for high-order harmonic generation in a gas, with repetition rates around 100 MHz.

TL;DR: This work proposes a model for the sensitivity of a cavity design to thermal deformations of the mirrors due to the high circulating powers and demonstrates average power improvement of one order of magnitude compared to state-of-the-art systems with similar pulse durations.

TL;DR: In this paper, a cavity-enhanced high-order harmonic generation (HHG) at a repetition rate of 250 MHz with 30fs pulses and an average power of 10kW was presented.

TL;DR: This work addresses the design of robust optical resonators with large spot sizes on all mirrors, a measure that promises to mitigate this limitation by decreasing both the intensity and the thermal gradient on the mirror surfaces by introducing a misalignment sensitivity metric to evaluate the robustness of resonator designs.

TL;DR: In this article, the authors proposed a temporal coherent combination (pulse stacking) of a pulse train emitted from a high-repetition-rate femtosecond laser system in a passive enhancement cavity.
