Absolute Length Sensing in a Long-Baseline, High-Finesse Optical Cavity
Todd Kozlowski, Henry Frädrich, Aaron D. Spector
The paper presents a method using two phase‑locked lasers to continuously measure the absolute length of a 123 m high‑finesse optical cavity with sub‑micron precision, enabling nan…
Demonstration of an interferometric technique for measuring vacuum magnetic birefringence with an optical cavity
Aaron D. Spector, Todd Kozlowski, Laura Roberts
Vacuum magnetic birefringence (VMB) is an effect predicted by quantum electrodynamics, in which the vacuum behaves as a non-linear optical medium and exhibit a birefringence in the…
Any Light Particle Searches with ALPS II: Description of the first science campaign
Aaron D. Spector, Daniel C. Brotherton, Ayman Hallal +23
From February to May of 2024 the Any Light Particle Search II (ALPS II) conducted its first science campaign using the `light-shining-through-a-wall' technique to search for pseudo…
Any Light Particle Searches with ALPS II: first science results
Daniel C. Brotherton, Zachary R. Bush, Sandy Croatto +37
The light-shining-through-a-wall experiment ALPS II at DESY in Hamburg searched for axions and similar lightweight particles in its first science campaign from February to May 2024…
Polarimetric searches for axion dark matter and high-frequency gravitational waves using optical cavities
Camilo GarcÃa-Cely, Luca Marsili, Andreas Ringwald +1
We revisit birefringence effects associated with the evolution of the polarization of light as it propagates through axion dark matter or the background of a passing gravitational…
