2025-08-13 THz waveform shifting and broadening along a DC electric field biased femtosecond laser plasma filament doi:10.57760/sciencedb.29055 en Longitudinally resolved terahertz radiations from tip-electrodes DC electric field biased laser filament were generated. The terahertz waveform undergoes a shifting of 0.43 ps and broadening of 0.46 ps in the time domain during its propagation in the 40 mm long filament. Both experimental and numerical results have proved that the propagation of THz in a DC-biased filament waveguide leading to the terahertz waveform shifting and broadening. terahertz; DC-biased filament; waveform shifting and broadening Juan Long Tiejun Wang Yaoxiangliu Yingxiawei Chaopengyang Xianwangli Rao Adeel Un Nabi Yingxu Yuxinleng PUBLIC https://creativecommons.org/publicdomain/zero/1.0/ dataset Science Data Bank
