Revealing the terahertz-laser velocity effect during air filamentation via travelling-wave-antenna model
Jiajun Yang, Xiaofeng Li, Linlin Yuan +2
During femtosecond laser filamentation in air, the velocity ratio (K) between the terahertz (THz) phase velocity and the laser group velocity plays a crucial role in THz waves gene…
