Journal ArticleDOI
A compact synchrotron radiation source driven by a laser-plasma wakefield accelerator
Hans-Peter Schlenvoigt,K. Haupt,Alexander Debus,F. Budde,O. Jäckel,Sebastian M. Pfotenhauer,Heinrich Schwoerer,Heinrich Schwoerer,Erich G. Rohwer,J. G. Gallacher,Enrico Brunetti,Richard Shanks,Sally Wiggins,Dino A. Jaroszynski +13 more
TL;DR: In this paper, the first successful combination of a laser-plasma wakefield accelerator with an undulator to generate visible synchrotron radiation was demonstrated, and the authors showed the potential for ultracompact and versatile laser-based radiation sources from the infrared to X-ray energies.
Journal ArticleDOI
Coherent octave spanning near-infrared and visible supercontinuum generation in all-normal dispersion photonic crystal fibers.
Alexander M. Heidt,Alexander Hartung,Gurthwin Bosman,Patrizia Krok,Erich G. Rohwer,Heinrich Schwoerer,Hartmut Bartelt +6 more
TL;DR: The first detailed demonstrations of octave-spanning SC generation in all-normal dispersion photonic crystal fibers (ANDi PCF) in the visible and near-infrared spectral regions are presented, presenting the broadest spectra generated in the normal dispersion regime of an optical fiber.
Journal ArticleDOI

Rohwer,Ruru Deng,Rodanthi-Elisavet Mamouri,Felix Zamorano +49 more
TL;DR: PollyNET as mentioned in this paper consists of portable, remote-controlled multiwavelength-polarization-Raman lidars (Polly) for automated and continuous 24/7 observations of clouds and aerosols.
Journal ArticleDOI
High quality sub-two cycle pulses from compression of supercontinuum generated in all-normal dispersion photonic crystal fiber
Alexander M. Heidt,Jan Rothhardt,Alexander Hartung,Hartmut Bartelt,Erich G. Rohwer,Jens Limpert,Andreas Tünnermann +6 more
TL;DR: Numerical simulations in excellent agreement with the experimental results are used to discuss the scalability of the concept to the single-cycle regime employing active phase shaping, and it is shown that previously reported limits to few-cycle pulse generation from compression of SC spectra generated in conventional PCF possessing one or more zero dispersion wavelengths do not apply for ANDi PCF.
Journal ArticleDOI
Contrasting the impact of aerosols at northern and southern midlatitudes on heterogeneous ice formation
Thomas Kanitz,Patric Seifert,Albert Ansmann,Ronny Engelmann,Dietrich Althausen,C. Casiccia,Erich G. Rohwer +6 more
TL;DR: In this paper, the occurrence of heterogeneous ice formation (as a function of cloud top temperature) for very different aerosol conditions in the northern and southern hemisphere is investigated, and large differences in the heterogeneous freezing behavior in mostly layered clouds are found.
