Imaging and Identification of Single Nanoplastic Particles and Agglomerates
Ambika Shorny, Fritz Steiner, Helmut Hörner +1
Currently the extent of nanoplastic in the environment can only be estimated by extrapolation from the plastic waste that can be detected. To be able to quantify the whole extent o…
Properties of quantum emitters in different hBN sample types particularly suited for nanophotonic integration
Ambika Shorny, Hardy Schauffert, James C. Stewart +11
Single photon emitters in two-dimensional (2D) hexagonal boron nitride (hBN) are promising solid-state quantum emitters for photonic applications and quantum networks. Despite thei…
Thermal tuning of a fiber-integrated Fabry-Pérot cavity
Clemens Singer, Alexander Goetz, Adarsh S. Prasad +3
Here, we present the thermal tuning capability of an alignment-free fiber-integrated Fabry-Pérot cavity.The two mirrors are made of fiber Bragg gratings that can be individually te…
Sonochemical synthesis of large two-dimensional Bi2O2CO3 nanosheets for hydrogen evolution in photocatalytic water splitting
Tushar Gupta, Nicole Rosza, Markus Sauer +10
Laterally large (~3 micrometers), atomically-thin two-dimensional (2D) Bi2O2CO3 nanosheets (2D bismuth oxycarbonate, 2D bismutite) are fabricated via sonochemically-assisted templa…
Nanofiber-based high-Q microresonator for cryogenic applications
Johanna Hütner, Thomas Hoinkes, Martin Becker +3
We demonstrate a cryo-compatible, fully fiber-integrated, alignment-free optical microresonator. The compatibility with low temperatures expands its possible applications to the wi…
A buffer gas beam source for short, intense and slow molecular pulses
S. Truppe, M. Hambach, S. M. Skoff +6
Experiments with cold molecules usually begin with a molecular source. We describe the construction and characteristics of a cryogenic buffer gas source of CaF molecules. The sourc…
Optical-nanofiber-based interface for single molecules
Sarah M. Skoff, David Papencordt, Hardy Schauffert +2
Optical interfaces for quantum emitters are a prerequisite for implementing quantum networks. Here, we couple single molecules to the guided modes of an optical nanofiber. The mole…
Characterization of a cryogenic beam source for atoms and molecules
N. E. Bulleid, S. M. Skoff, R. J. Hendricks +3
We present a combined experimental and theoretical study of beam formation from a cryogenic buffer gas cell. Atoms and molecules are loaded into the cell by laser ablation of a tar…
Franck-Condon Factors and Radiative Lifetime of the A^{2}Π_{1/2} - X^{2}Σ^{+} Transition of Ytterbium Monoflouride, YbF
Xiujuan Zhuang, Anh Le, Timothy C. Steimle +8
The fluorescence spectrum resulting from laser excitation of the A^{2}Π_{1/2} - X^{2}Σ^{+} (0,0) band of ytterbium monofluoride, YbF, has been recorded and analyzed to determine th…
Diffusion, thermalization and optical pumping of YbF molecules in a cold buffer gas cell
S. M. Skoff, R. J. Hendricks, C. D. J. Sinclair +5
We produce YbF molecules with a density of 10^18 m^-3 using laser ablation inside a cryogenically-cooled cell filled with a helium buffer gas. Using absorption imaging and absorpti…
Doppler-free laser spectroscopy of buffer gas cooled molecular radicals
S. M. Skoff, R. J. Hendricks, C. D. J. Sinclair +5
We demonstrate Doppler-free saturated absorption spectroscopy of cold molecular radicals formed by laser ablation inside a cryogenic buffer gas cell. By lowering the temperature, c…
