The Raspberry Pi Auto-aligner: Machine Learning for Automated Alignment of Laser Beams
Renju S. Mathew, Roshan O'Donnell, Danielle Pizzey +1
We present a novel solution to automated beam alignment optimization. This device is based on a Raspberry Pi computer, stepper motors, commercial optomechanics and electronic devic…
Atomic line versus lens cavity filters: A comparison of their merits
Clare R. Higgins, Danielle Pizzey, Renju S. Mathew +1
We present a comparison between lens cavity filters and atomic line filters, discussing their relative merits for applications in quantum optics. We describe the design, characteri…
Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen--Back regime
Renju S. Mathew, Francisco Ponciano-Ojeda, James Keaveney +2
We demonstrate a technique to lock simultaneously two laser frequencies to each step of a two-photon transition in the presence of a magnetic field sufficiently large to gain acces…
Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen-Back regime
Daniel J. Whiting, Renju S. Mathew, James Keaveney +2
We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S, 5P, 5P and 5D terms) i…
Effect of line broadening on the performance of Faraday filters
Mark A. Zentile, Renju S. Mathew, Daniel J. Whiting +3
We show that homogeneous line broadening drastically affects the performance of atomic Faraday filters. We use a computerized optimization algorithm to find the best magnetic field…
