500 W rod-type 4x4 multi-core ultrafast fiber laser
A. Klenke, A. Steinkopff, C. Aleshire +10
We present a coherently-combined femtosecond fiber CPA system based on a rod-type, Ytterbium-doped, multicore fiber with 4x4 cores. A high average power of up to 500 W (after combi…
Experimental Investigations on the TMI Thresholds of Low-NA Yb-doped single mode fibers
Franz Beier, Friedrich Moeller, Bettina Sattler +9
In this contribution we investigate the transversal mode instability behavior of an ytterbium doped commercial 20/400 fiber and obtain 2.9 kW of output power after optimizing the i…
Laser-induced anti-Stokes fluorescence cooling of ytterbium-doped silica glass by more than 6 Kelvin
Mostafa Peysokhan, Saeid Rostami, Esmaeil Mobini +12
Laser cooling of a solid is achieved when a coherent laser illuminates the material, and the heat is extracted by resulting anti-Stokes fluorescence. Over the past year, net solid-…
Silicon microcavity arrays with open access and a finesse of half a million
G. Wachter, S. Kuhn, S. Minniberger +10
Optical resonators are increasingly important tools in science and technology. Their applications range from laser physics, atomic clocks, molecular spectroscopy, and single-photon…
Probing Macroscopic Quantum Superpositions with Nanorotors
Benjamin A. Stickler, Birthe Papendell, Stefan Kuhn +4
Whether quantum physics is universally valid is an open question with far-reaching implications. Intense research is therefore invested into testing the quantum superposition princ…
Nanoparticle detection in an open-access silicon microcavity
Stefan Kuhn, Georg Wachter, Franz-Ferdinand Wieser +6
We report on the detection of free nanoparticles in a micromachined, open-access Fabry-Pérot microcavity. With a mirror separation of m, a radius of curvature of mm,…
