A monolithic segmented 3D ion trap fabricated from fused silica by selective laser-induced etching
Edgar Brucke, Martin Wagener, Moritz Fontboté-Schmidt +10
We present the design, fabrication, and characterization of a monolithic, segmented, three-dimensional linear Paul ion trap for quantum science applications. The trap is fabricated…
High-NA vectorial hologram optimization
Michael Wischert, Fiona Hellstern, Paul Uerlings +3
We present a vectorial phase-only framework for the gradient-based optimization of computer-generated holograms. Our approach addresses a critical limitation in high numerical aper…
Two-dimensional shelving spectroscopy of ultraviolet ground state transitions in dysprosium
Kevin S. H. Ng, Paul Uerlings, Fiona Hellstern +5
The open inner-shell electronic structure of lanthanides with large magnetic moments gives rise to a rich spectrum of transitions available for laser cooling, trapping, and coheren…
Modular variable laser cooling for efficient entropy extraction
Brennan de Neeve, Thanh-Long Nguyen, Alexander Ferk +5
We propose and experimentally demonstrate a method for laser cooling an oscillator based on sequences of spin-state-dependent displacements followed by spin repumping. For a therma…
