Dielectric Resonator Reflectarray as High-Efficiency Nonuniform Terahertz Metasurface

Advances in terahertz technology rely on the combination of novel materials and designs. As new devices are demonstrated to address the terahertz gap, the ability to perform high-efficiency beam control will be integral to making terahertz radiation a prac ...

Probing the coupling between a doublon excitation and the charge-density wave in TaS2 by ultrafast optical spectroscopy

Arnaud Magrez, Fabrizio Carbone, Helmuth Berger, Edoardo Baldini, Andreas Helmut Christian Mann, Ahmad Odeh

Recently, the switching between the different charge-ordered phases of 1T-TaS2 has been probed by ultrafast techniques, revealing unexpected phenomena such as "hidden" metastable states and peculiar photoexcited charge patterns. Here, we apply broadband pu ...

Short X-ray pulses from third-generation light sources

Christoph Peter Hauri

High-brightness X-ray radiation produced by third-generation synchrotron light sources (TGLS) has been used for numerous time-resolved investigations in many different scientific fields. The typical time duration of X-ray pulses delivered by these large-sc ...

Laser-Assisted Photoelectric Effect from Liquids

Majed Chergui, Frank van Mourik, Christopher Alexander Arrell, Lars-Hendrik Mewes, José Javier Pancracio Ojeda Andara, Jakob Grilj

The laser-assisted photoelectric effect from liquid surfaces is reported for the first time. Photoelectrons generated by 35.6 eV radiation from a liquid microjet of water under vacuum are dressed with (h) over bar omega = 1.55 eV laser field. The subsequen ...

Increased Photoconductivity Lifetime in GaAs Nanowires by Controlled n-Type and p-Type Doping

Anna Fontcuberta i Morral, Federico Matteini, Alberto Casadei, Fauzia Jabeen

Controlled doping of GaAs nanowires is crucial for the development of nanowire-based electronic and optoelectronic devices. Here, we present a noncontact method based on time resolved terahertz photoconductivity for assessing n- and p-type doping efficienc ...

High-power femtosecond Raman frequency shifter

Christoph Peter Hauri, Mostafa Shalaby

We report on the generation of broadband, high-energy femtosecond pulses centered at 1.28 mu m by stimulated Raman scattering in a pressurized hydrogen cell. Stimulated Raman scattering is performed by two chirped and delayed pulses originating from a mult ...

Simulation of FEL pulse length calculation with THz streaking method

Ishkhan Gorgisyan

Having accurate and comprehensive photon diagnostics for the X-ray pulses delivered by free-electron laser (FEL) facilities is of utmost importance. Along with various parameters of the photon beam (such as photon energy, beam intensity, etc.), the pulse l ...

Beyond Vibrationally Mediated Electron Transfer: Coherent Phenomena Induced by Ultrafast Charge Separation

Jacques-Edouard Moser

Wave packet propagation succeeding electron transfer (ET) from alizarin dye molecules into the nanocrystalline TiO2 semiconductor has been studied by ultrafast transient absorption spectroscopy. Because of the ultrafast time scale of the ET reaction of abo ...
