Journal ArticleDOI
Discrete nonplanar reflections from an ultrashort pulse written volume Bragg grating.
Daniel Richter,Christian Voigtländer,Ria G. Krämer,Jens Thomas,Andreas Tünnermann,Stefan Nolte +5 more
TL;DR: An algorithm to predict the grating pattern and its diffraction behavior under collimated, spectral broad illumination is developed and the predicted data are in good agreement with the measurements.
Journal ArticleDOI
Potential mechanical loss mechanisms in bulk materials for future gravitational wave detectors
D. Heinert,Alexander Grib,K. Haughian,J. H. Hough,Stefanie Kroker,P. G. Murray,Ronny Nawrodt,Ronny Nawrodt,Sheila Rowan,C. Schwarz,Paul Seidel,Andreas Tünnermann +11 more
TL;DR: In this paper, the authors present an analysis of the contribution of Akhieser and thermoelastic damping on the experimental results of resonant mechanical loss measurements, showing that the combination of both processes allows the fit of the experimental data of quartz in the low temperature region (10K to 25K).
Proceedings ArticleDOI
Design of a THz optics for a 128 channel THz imaging system
TL;DR: In this paper, the design for a 128 channel ultrashort THz pulse imaging system is presented, where biconic and aspherical surfaces are used for diffraction limited imaging a 64 mm-field.
Journal ArticleDOI
Erratum: Observation of Three-Dimensional Discrete-Continuous X Waves in Photonic Lattices [Phys. Rev. Lett. 103, 113903 (2009)]
Matthias Heinrich,Alexander Szameit,Felix Dreisow,Robert Keil,Stefano Minardi,Thomas Pertsch,Stefan Nolte,Andreas Tünnermann,Falk Lederer +8 more
Proceedings ArticleDOI
Time-resolved microscopy for optimizing in-volume glass processing using ultra short laser pulses
TL;DR: In this article, the free electron densities within the laser-induced plasma are linked to the types of modifications that can be tailored inside a transparent material to obtain defect states and cracks.
