Systematic Study of Amorphous ABC Heterostructures at the Atomic Scale as a Second-Order Nonlinear Optical Metamaterial
Martin Mičulka, Jinsong Liu, Sebastian Beer +10
Systematic exploration of amorphous ABC heterostructures revealed that nanoscale morphological modifications markedly improved their artificial bulk second-order susceptibility. Th…
Atomically Thin Metal-Dielectric Heterostructures by Atomic Layer Deposition
Pallabi Paul, Paul Schmitt, Vilborg Vala Sigurjonsdottir +9
Heterostructures increasingly attracted attention over the past several years to enable various optoelectronic and photonic applications. In this work, atomically thin interfaces o…
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…
Towards metropolitan free-space quantum networks
Andrej Kržič, Sakshi Sharma, Christopher Spiess +18
Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre based systems h…
Monolithic Thulium Fiber Laser with 567 W output power at 1970 nm
Till Walbaum, Matthias Heinzig, Thomas Schreiber +2
We report on a monolithic thulium fiber laser with 567 W output power at 1970 nm, which is the highest power reported so far directly from a thulium oscillator. This is achieved by…
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-…
