Symmetry-Breaking Electron Dynamics Enable Ultrabroadband Optical-Field Sampling via Second-Harmonic Generation
Wenqi Tang, Ahai Chen, Michael Klaiber +4
Optical-field sampling using second-harmonic generation (SHG) from strong-field ionization enables ultrabroadband terahertz detection, but the microscopic origin of the SHG signal…
Experimental Realization of All-Optical Terahertz Attoclock
Yanjun Gao, Yizhu Zhang, Yulin Chen +8
The attoclock is a powerful tool for probing ultrafast electron dynamics with attosecond precision.Here, we demonstrate an all-optical terahertz (THz) attoclock that reconstructs p…
Probing Electronic Motion and Core Potential by Coulomb-reshaped Terahertz Radiation
Ziyang Gan, Kaixuan Zhang, Yuan Gao +5
The nature of electronic motion and structural information of atoms and molecules is encoded into strong-field induced radiations ranging from terahertz (THz) to extreme ultraviole…
Temporal-Spatial Manipulation of Bi-Focal Bi-Chromatic Fields for Terahertz Radiations
Jingjing Zhao, Yizhu Zhang, Yanjun Gao +5
Mixing the fundamental () and the second harmonic (2) waves in gas phase is a widely employed technique for emitting terahertz (THz) pulses. The THz generation driven by bi…
