Air nonlinear dynamics initiated by ultra-intense lambda-cubic THz pulses
Mostafa Shalaby, Christoph P. Hauri
Air turns into a nonlinear medium for electromagnetic waves under exceptionally strong fields. However up to present, its minuscule nonlinear response has limited the exploration t…
Temporal and Spectral Shaping of Broadband THz Pulses in a Photoexcited Semiconductor
Mostafa Shalaby, Marco Peccianti, David G. Cooke +2
Transmission through photoexcited semiconductors is used to temporally and spectrally shape a Terahertz pulse. By adjusting the optical pump-THz probe delay, we experimentally intr…
Terahertz Magnetic Modulator based on Magnetically-Clustered Nanoparticles
Mostafa Shalaby, Marco Peccianti, Yavuz Ozturk +3
Random orientation of liquid-suspended magnetic nanoparticles (Ferrofluid) gives rise to zero net magnetic orientation. An external magnetic field tends to align them into clusters…
Tailoring single-cycle electromagnetic pulses in the 2-9 THz frequency range using DAST/SiO2 multilayer structures pumped at Ti:sapphire wavelength
Andrei G. Stepanov, Andrii Rogov, Luigi Bonacina +2
We present a numerical parametric study of single-cycle electromagnetic pulse generation in a DAST/SiO2 multilayer structure via collinear optical rectification of 800 nm femtoseco…
Intense multi-octave supercontinuum pulses from an organic emitter covering the entire THz frequency gap
C. Vicario, B. Monoszlai, M. Jazbinsek +3
In Terahertz (THz) technology, one of the long-standing challenges has been the formation of intense pulses covering the hard-to-access frequency range of 1-15 THz (so-called THz g…
Terahertz brightness at the extreme: demonstration of 5 GV/m, 17 T low frequency λ3 terahertz bullet
Mostafa Shalaby, Christoph P. Hauri
The brightness of a light source defines its applicability to nonlinear phenomena in science. Bright low frequency terahertz (< 5THz) radiation confined to a diffraction-limited sp…
