论文摘要
半经典电子轨迹，即所谓的量子轨道，用于解释双色强场中的Terahertz波产生（TWG），该理论的可行性通过测量值验证。我们发现TWG源于在双色电场的相邻周期中释放的部分电子波袋的量子路径干扰，这表明了颞杨的单张双缝线干扰单电子。从相邻周期中释放的轨迹，创建TWG，还考虑了光电子动量分布中的循环间干扰条纹，而仅在单个周期中进行轨迹时，找不到TWG的签名。
The semiclassical electron trajectory, the so-called quantum orbits, is employed to explain the terahertz wave generation (TWG) in dual-color strong field, and the feasibility of the theory is validated by the measurement. We find that TWG stems from quantum path interference of partial electron wavepacket released at the neighbouring cycles of the dual-color electric field, manifesting the temporal Young's double-slit interference of single electron. The trajectories released from neighbouring cycles, creating TWG, also account for intercycle interference fringes in the photoelectron momentum distribution, whereas no signature of TWG is found when taking trajectories only from a single cycle.
