Temperature-Dependent THz Properties and Emission of Organic Crystal BNA
Samira Mansourzadeh, Tim Vogel, Mostafa Shalaby +1
As high-average power ultrafast lasers become increasingly available for nonlinear conversion, the temperature dependence of the material properties of nonlinear crystals becomes i…
Efficient broadband THz generation in BNA organic crystal at Ytterbium laser wavelength
Hovan Lee, Claudia Gollner, Jiaqi Nie +3
In this work, we demonstrate BNAs high potential for efficient generation of high power THz using ytterbium laser wavelengths. We study the generation theoretically and experimenta…
Real-time High Resolution THz Imaging with a Fiber Coupled Photo Conductive Antenna and an Uncooled Microbolometer Camera
Peter Zolliker, Mostafa Shalaby, Elisa Söllinger +2
We present a real-time THz imaging method using a commercial fiber coupled photo conductive antenna as the THz source and an uncooled microbolometer camera for detection. Compared…
A multi-milliJoule femtosecond Raman laser emitting at 1.28 um
Carlo Vicario, Mostafa Shalaby, Aleksandr Konyashchenko +2
We report on the generation of broadband, high-energy femtosecond pulses centered at 1.28 um by stimulated Raman scattering in pressurized hydrogen cell. Stimulated Raman scatterin…
The terahertz frontier for ultrafast coherent magnetic switching: Terahertz-induced demagnetization in ferromagnets
Mostafa Shalaby, Carlo Vicario, Christoph P. Hauri
The transition frequency between nonthermal coherent magnetic precessions and ultrafast demagnetization is arguably the most sought after answer in magnetism science and technology…
Anomalous visualization of sub-2 THz photons on standard silicon CCD and COMS sensors
Mostafa Shalaby, Carlo Vicario, Christoph P. Hauri
We experimentally show that indirect light-induced electron transitions could lead to THz detection on standard CCD and CMOS sensors, introducing this well-established technologica…
