AI 中文摘要
阿秒量子光由强量子光驱动的高次谐波叠加形成，为探测物质中的量子力学关联开辟了新途径。本研究中，我们研究了强相干光与弱明亮压缩真空（BSV）激光与原子气体相互作用产生的量子高次谐波的宏观传播效应。结果表明，吸收或发射BSV光子产生的谐波的压力依赖强度不同于仅使用强相干脉冲产生的谐波。宏观传播模拟表明，弱BSV脉冲会扰动谐波的作用相位。这种扰动会调制亚周期阿秒脉冲串的相位失配，并在气压变化时影响其量子特性。产生明亮量子高次谐波的能力为阿秒量子光谱学的建立和应用奠定了基础。
英文摘要
Attosecond quantum light, formed by the superposition of high-order harmonics driven by intense quantum light, opens new routes to probe quantum-mechanical correlations in matter. In this study, we have investigated the macroscopic propagation effects of quantum high-order harmonics generated by the combination of strong coherent and weak bright squeezed vacuum (BSV) lasers interacting with atomic gas. Our results reveal that the pressure-dependent intensity of harmonics arising from absorbing or emitting BSV photons differs from that of harmonics generated using only strong coherent pulses. Macroscopic propagation simulations indicate that the action phase of harmonics is perturbed by the weak BSV pulses. This perturbation modulates the phase mismatch of sub-cycle attosecond bursts and affects their quantum properties when the gas pressure varies. The ability to generate bright quantum high-order harmonics lays a foundation for the establishment and application of attosecond quantum spectroscopy.
