Klaus Ehret,Maik Frede,Samvel Ghazaryan,Matthias Hildebrandt,Ernst-Axel Knabbe,Dietmar Kracht,Axel Lindner,Jenny List,T. Meier,N. Meyer,Dieter Notz,Javier Redondo,Andreas Ringwald,Günter Wiedemann,Benno Willke +14 more
TL;DR: The ALPS experiment as discussed by the authors runs a Light Shining through a Wall (LSW) experiment to search for photon oscillations into weakly interacting sub-eV Particles (WISPs) often predicted by extensions of the Standard Model.
Journal ArticleDOI

Klaus Ehret,Maik Frede,Samvel Ghazaryan,Matthias Hildebrandt,Ernst-Axel Knabbe,Dietmar Kracht,Axel Lindner,Jenny List,T. Meier,N. Meyer,Dieter Notz,Javier Redondo,Andreas Ringwald,Günter Wiedemann,Benno Willke +14 more
TL;DR: In this article, the first successful integration of a large-scale optical resonant cavity to boost the available power for WISP production in this type of experiments is reported, where the key elements are a frequency tunable narrow line-width continuous wave laser acting as the primary light source and an electronic feed-back control loop to stabilize the power build-up.
Journal ArticleDOI
Brillouin scattering spectra in high-power single-frequency ytterbium doped fiber amplifiers.
TL;DR: Experimental and theoretical investigations on spontaneous and stimulated Brillouin scattering during operation of a high-power single-frequency polarization-maintaining ytterbium doped fiber amplifier and their results have been compared with a theoretical model based on coupled intensity equations.
Journal ArticleDOI
Single-frequency master-oscillator photonic crystal fiber amplifier with 148 W output power
TL;DR: A high-power ytterbium doped photonic crystal fiber amplifier using a single-frequency Nd:YAG non-planar ring oscillator seed source and sensitive beam quality measurements with a Fabry-Perot ring-cavity are presented.
Journal ArticleDOI
Narrow-linewidth ytterbium-doped fiber amplifier system with 45 nm tuning range and 133 W of output power.
TL;DR: A master-oscillator ytterbium-doped fiber amplifier system with up to 133 W of continuous-wave output power using a tunable narrow-linewidth external-cavity diode laser seed source is reported on.
