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…
