Temporal-Spatial Manipulation of Bi-Focal Bi-Chromatic Fields for Terahertz Radiations

Jingjing Zhao, Yizhu Zhang, Yanjun Gao +5

Mixing the fundamental ($\ddot{I}‰$) and the second harmonic (2$\ddot{I}‰$) waves in gas phase is a widely employed technique for emitting terahertz (THz) pulses. The THz generation driven by bi…
