Using the optical-klystron effect to increase and measure the intrinsic beam energy spread in free-electron-laser facilities

Eugenio Ferrari, Thomas Schietinger, Sven Reiche

We present a setup based on the optical klystron concept, consisting of two undulator modules separated by a magnetic chicane, that addresses two issues in free-electron-laser (FEL) facilities. On the one hand, it allows increasing the intrinsic energy spr ...

Charge migration and charge transfer in molecular systems

Majed Chergui, Ursula Röthlisberger, Jacques-Edouard Moser, Andrea Cannizzo, Natalie Renuka Banerji, Joël Teuscher, Christopher Alexander Arrell, Pablo Lopez Tarifa, Elisa Liberatore

The transfer of charge at the molecular level plays a fundamental role in many areas of chemistry, physics, biology and materials science. Today, more than 60 years after the seminal work of R. A. Marcus, charge transfer is still a very active field of res ...

Nonadiabatic effects in electronic and nuclear dynamics

Majed Chergui, Ursula Röthlisberger, Jiri Vanicek, Martin Peter Bircher, Tomas Zimmermann, Elisa Liberatore, Aurélien Kevin Fabrice Patoz, Nicholas John Browning

Due to their very nature, ultrafast phenomena are often accompanied by the occurrence of nonadiabatic effects. From a theoretical perspective, the treatment of nonadiabatic processes makes it necessary to go beyond the (quasi) static picture provided by th ...

Bringing short-lived dissipative Kerr soliton states in microresonators into a steady state

Tobias Kippenberg, Victor Brasch, Michael Wolfgang Geiselmann, Martin Hubert Peter Pfeiffer

Dissipative Kerr solitons have recently been generated in optical microresonators, enabling ultrashort optical pulses at microwave repetition rates, that constitute coherent and numerically predictable Kerr frequency combs. However, the seeding and excitat ...

Polarization mode control of long-wavelength VCSELs by intracavity patterning

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Christopher Michael Long

Polarization mode control is enhanced in wafer-fused verticalcavity surface-emitting lasers emitting at 1310 nm wavelength by etching two symmetrically arranged arcs above the gain structure within the laser cavity. The intracavity patterning introduces bi ...

Ultrafast Photoelectron Spectroscopy of Liquid Samples

José Javier Pancracio Ojeda Andara

This thesis focuses on the commissioning and characterization of HARMONIUM, an ultrafast tunable EUV source based on high-harmonic generation for performing photoelectron spectroscopy of liquids. In ultrafast photoelectron spectroscopy a short pump pulse i ...

W-Band Waveguide Filters Fabricated by Laser Micromachining and 3-D Printing

Emile Jacques de Rijk, Mathieu Billod, Cheng Guo

This paper presents two W-band waveguide bandpass filters, one fabricated using laser micromachining and the other 3-D printing. Both filters are based on coupled resonators and are designed to have a Chebyshev response. The first filter is for laser micro ...

Experimental verification of the method for producing a three-dimensional cross-pairs metamaterial structure based on a dielectric AlN cube

Przemyslaw Andrzej Gorski

This paper presents a method of manufacturing 3D metamaterial structures using laser radiation. Our proposed material, aluminum nitride (AlN), by interaction of a high-energy laser beam undergoes a direct metallization process, a result of which a conducti ...

Terahertz-induced demagnetization in ferromagnets

Christoph Peter Hauri, Mostafa Shalaby

We experimentally demonstrate ultrafast terahertz induced demagnetization in conducting ferromagnets, Ni, Co, and Fe. At even higher excitation fluence, the materials lose their magnetic properties and then get damaged before magnetic switching takes place ...
