Relativistic interaction of long-wavelength ultrashort laser pulses with nanowires

Z. Samsonova, S. Höfer, V. Kaymak +11

We report on experimental results in a new regime of a relativistic light-matter interaction employing mid-infrared (3.9-micrometer wavelength) high-intensity femtosecond laser pul…

Table-top Nonlinear Extreme Ultraviolet Spectroscopy

T. Helk, E. Berger, S. Jamnuch +12

The lack of available table-top extreme ultraviolet (XUV) sources with high enough fluxes and coherence properties have limited the availability of nonlinear XUV and x-ray spectros…

Nonlinear Ionization Dynamics of Hot Dense Plasma Observed in a Laser-Plasma Amplifier

F. Tuitje, P. Martínez Gil, T. Helk +9

From fusion dynamics in stars, to terrestrial lightning events, to new prospects of energy production or novel light sources, hot dense plasmas are of importance for an array of ph…

High Speed and High Resolution Table-Top Nanoscale Imaging

G. K. Tadesse, R. Klas, S. Demmler +8

We present a table-top coherent diffraction imaging (CDI) experiment based on high-order harmonics generated at 18 nm by a high average power femtosecond fiber laser system. The hi…

Generation of keV hot near-solid density plasma states at high contrast laser-matter interaction

O. N. Rosmej, Z. Samsonova, S. Höfer +13

We present experimental evidence of ultra-high energy density plasma states with the keV bulk electron temperatures and near-solid electron densities generated during the interacti…

Direct observation of the injection dynamics of a laser wakefield accelerator using few-femtosecond shadowgraphy

A. Sävert, S. P. D. Mangles, M. Schnell +13

We present few-femtosecond shadowgraphic snapshots taken during the non-linear evolution of the plasma wave in a laser wakefield accelerator with transverse synchronized few-cycle…

Tracing spatial confinement in semiconductor quantum dots by high-order harmonic generation

H. N. Gopalakrishna, R. Baruah, C. Hünecke +20

We report here on results of experimental-theoretical investigation of high-order harmonic generation (HHG) in layers of CdSe semiconductor quantum dots of different sizes and a re…
