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…
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-c…
Coulomb potential determining terahertz polarization in two-color laser field
Yuan Gao, Yizhu Zhang, Kaixuan Zhang +3
The orientation and ellipticity of terahertz (THz) polarization generated by two-color strong field not only cast light on underlying mechanisms of laser-matter interaction, but al…
Intensity-surged and Bandwidth-extended Terahertz Radiation in Two-foci Cascading Plasmas
Yizhu Zhang, Zhi-Hong Jiao, Tao He +7
The two-color strong-field mixing in gas medium is a widely-used approach to generate bright broadband terahertz (THz) radiation. Here, we present a new and counterintuitive method…
Terahertz field induced near-cutoff even-order harmonics in femtosecond laser
Bing-Yu Li, Yizhu Zhang, Tian-Min Yan +1
High-order harmonic generation by femtosecond laser pulse in the presence of a moderately strong terahertz (THz) field is studied under the strong field approximation, showing a si…
Terahertz generation in dual-color laser: continuum electron in strong-field single-atom ionization
Kaixuan Zhang, Yizhu Zhang, T. -M. Yan +1
The terahertz (THz) generation in a dual-color field was investigated experimentally by precisely controlling the relative time delay and polarization of dual-color lasers,…
Terahertz Wave Guiding by Femtosecond Laser Filament in Air
Jiayu Zhao, Yizhu Zhang, Zhi Wang +5
Femtosecond laser filament generates strong terahertz (THz) pulse in air. In this paper, THz pulse waveform generated by femtosecond laser filament has been experimentally investig…
