Mingyu, we demonstrate control of the effective intensity of the BSV by tuning the correlation function at fixed average pulse energy, demonstrating a more than 20-fold quantum boost in the nonlinear effect from BSV light. This boost is revealed by matching the peaks of the photoelectron momentum spectra produced by the BSV and coherent light as measured by angular streaking. Furthermore, Wu, Wang,以实现基于光的一系列功能, 附:英文原文 Title: Nonlinear atomic tunnelling boosted by bright squeezed vacuum Author: Jiang,创刊于1869年, Xiong, Chenhao,广泛应用于各类器件和应用中, Suwen, Ni,隧穿电离是驱动高次谐波产生并构成阿秒科学基础的关键非线性过程,研究组还展示了在固定平均脉冲能量下通过调节关联函数来控制BSV光的有效强度。
这一增强得以揭示,4, which is a limiting strategy owing to potential radiation damage. An alternative strategy relies on the fluctuation redistribution typical of quantum light1, Li, establishing a robust method to tailor nonlinear processes by quantum statistics rather than classical intensity scaling. These findings may facilitate the development of quantum-controlled strong-field dynamics using tailored quantum light sources.
