Laser Cooling of a Yb Doped Silica Fiber by 18 Kelvin From Room Temperature
Brian Topper, Mostafa Peysokhan, Alexander R. Albrecht +10
A ytterbium doped silica optical fiber has been cooled by 18.4K below ambient temperature by pumping with 20W of 1035nm light in vacuum. In air, cooling by 3.6K below ambient was o…
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…
Coherently combined 16 channel multicore fiber laser system
A. Klenke, M. Müller, H. Stark +5
We present a coherently combined laser amplifier with 16 channels from a multicore fiber in a proof-of-principle demonstration. Filled aperture beam splitting and combination toget…
