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…
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…
Magneto-photonic phenomena at terahertz frequencies
Mostafa Shalaby
Magneto-terahertz phenomena are the main focus of the thesis. This work started as supporting research for the science of an X-ray laser (SwissFEL). X-ray lasers have recently draw…
Skirting Terahertz Waves in a Photo-excited Nanoslit Structure
Mostafa Shalaby, Justyna Fabiańska, Marco Peccianti +5
Terahertz fields can be dramatically enhanced as they propagate through nanometer-sized slits. The enhancement is mediated by significant accumulation of the induced surface charge…
