Impact of the pump wavelength in THz emissions by two-color femtosecond laser filaments in air

Résumé

Laser filamentation is actively studied for its rich variety of applications, from supercontinuum generation to lightning control. In air, femtosecond filaments result from the self-focusing of ultrashort light pulses that couple to their own plasma channel and stay self-guided upon extended paths at high intensity levels. Driven by strong nonlinearities, these optical structures are able to promote broadband THz-to-far-infrared radiation when using laser fields composed of two colors, e.g., a fundamental and its second harmonic.
