Tobias Saule,Stephan Heinrich,Stephan Heinrich,Johannes Schötz,Johannes Schötz,Nikolai Lilienfein,Nikolai Lilienfein,Maximilian Högner,Maximilian Högner,O. deVries,M. Plötner,Johannes Weitenberg,Dominik Esser,Jan Schulte,Peter Russbueldt,Jens Limpert,Matthias F. Kling,Matthias F. Kling,Ulf Kleineberg,Ulf Kleineberg,Ioachim Pupeza +20 more
TL;DR: The measurement time reduction and the photon energy scalability render this technology viable for next-generation, high-repetition-rate, multidimensional attosecond metrology, and a large count rate improvement over state-of-the-art attose Cond setups under identical space charge conditions.
Proceedings ArticleDOI
Fabrication of longitudinally arbitrary shaped fiber tapers
Johannes Nold,M. Plötner,Steffen Böhme,Bettina Sattler,O. deVries,T. Schreiber,R. Eberhardt,A. Tünnermann +7 more
TL;DR: In this paper, the authors present results on the fabrication of arbitrary shaped fiber tapers on a tapering rig using a CO2-laser as heat source, which allows for reproducible fabrication of singlemode excitation tapers to extract the fundamental mode (M2 < 1.1) from a 30 μm core having an NA of 0.09.

Pupil slicer at high throughput for the EXtreme Precision Spectrograph (EXPRES) at the Lowell Discovery Telescope
Erik Beckert,Debra A. Fischer,Ryan T. Blackman,C. Jurgenson,O. deVries,Herbert Gross,R. Hambach +6 more
TL;DR: The free-space pupil slicer of Yale University's EXtreme PREcision Spectrograph (EXPRES) at Lowell Observatory's Lowell Discovery Telescope (LDT) is placed in the beam conditioning sub-system of the spectrograph in between fiber feeds for an incoming science fiber at octagonal core dimensions of 66 µm, and a respective outgoing rectangular fiber at half the width and twice the height of the octagonal fiber with core dimension of 132 x 33 µm2 as discussed by the authors .
Proceedings ArticleDOI
Towards a space-suitable wavelength-division multiplexer for 5-channel high-power long-range laser communication in the C-and L-band
Matthias Heinzig,Till Walbaum,Maximilian Strecker,Christoph Damm,O. deVries,Thomas Schreiber +5 more
TL;DR: In this paper , a module for spectral combination of five channels with an individual power of 20W each, designed for satellite-based communication, is presented, which is based on volume Bragg gratings, allowing for narrow spacing and combination without loss of neardiffraction-limited beam quality.
