Absolute Length Sensing in a Long-Baseline, High-Finesse Optical Cavity
Todd Kozlowski, Henry Frädrich, Aaron D. Spector
The relative phase between two lasers in transmission of an optical cavity can be used to continuously measure its absolute length with sub-micron precision. The first laser is kep…

Polarimetric searches for axion dark matter and high-frequency gravitational waves using optical cavities
Camilo García-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…

Design and Performance of the ALPS II Regeneration Cavity
Todd Kozlowski, Li-Wei Wei, Aaron D. Spector +12
The Regeneration Cavity (RC) is a critical component of the Any Light Particle Search II (ALPS II) experiment. It increases the signal from possible axions and axion-like particles…
