Terahertz pulse generation by two-color laser fields with circular polarization
C. Tailliez, A. Stathopulos, S. Skupin +4
We study the influence of the polarization states of femtosecond two-color pulses ionizing gases on the emitted terahertz radiation. A local-current model and plane-wave evaluation…

Terahertz vortex wave generation in air plasma by two-color femtosecond laser pulses
Maksym Ivanov, Illia Thiele, Luc Bergé +3
We investigate the generation of broadband terahertz (THz) pulses with phase singularity from air plasmas created by fundamental and second harmonic laser pulses. We show that when…
