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…
Spectral dynamics of THz pulses generated by two-color laser filaments in air: The role of Kerr nonlinearities and pump wavelength
A. Nguyen, P. Gonzalez de Alaiza Martinez, J. Dechard +4
We theoretically and numerically study the influence of both instantaneous and Raman-delayed Kerr nonlinearities as well as a long-wavelength pump in the terahertz (THz) emissions…
Boosting terahertz generation in laser-field ionized gases using a sawtooth wave shape
P. González de Alaiza Martínez, I. Babushkin, L. Bergé +6
Broadband ultrashort terahertz (THz) pulses can be produced using plasma generation in a noble gas ionized by femtosecond two-color pulses. Here we demonstrate that, by using multi…
Tailoring THz radiation by controlling tunnel photoionization events in gases
I. Babushkin, S. Skupin, A. Husakou +4
Applications ranging from nonlinear terahertz spectroscopy to remote sensing require broadband and intense THz radiation which can be generated by focusing two-color laser pulses i…
Ultrafast spatio-temporal dynamics of terahertz generation by ionizing two-color femtosecond pulses in gases
I. Babushkin, W. Kuehn, C. Koehler +6
We present a combined theoretical and experimental study of spatio-temporal propagation effects in terahertz (THz) generation in gases using two-color ionizing laser pulses. The ob…
