Laser-plasma accelerator optimization through active stabilization of the 100-TW-class high-power laser delivery to focus
ORAL
Abstract
The control of position and pointing angle of high-power laser pulses at focus allows for stability and tunability of applications such as laser-plasma acceleration, and other high-intensity-laser and laser-plasma interactions. While recently we have published a non-perturbative high-power diagnostic based on a rear-surface wedged final steering optic [Isono et al. High Power Laser Sci. Eng. 9, e25 (2021)], we now present concepts and experimental progress on complimenting this diagnostic with active stabilization for both position and angle. The availability of a kHz non-amplified pulse train in conjunction with the amplified 1 Hz pulses will be discussed in the context of active feedback concepts. Improvements to laser-plasma acceleration enabled with these new control capabilities are investigated.
