Interference Fringe Mitigation in Short-Delay Self-Heterodyne Laser Phase Noise Measurements
Jasper Riebesehl, David C. Nak, Darko Zibar
Self-heterodyne techniques are widely used for laser phase noise characterization due to their simple experimental setup and the removed need for a reference laser. However, when i…

Single-site-resolved imaging of ultracold atoms in a triangular optical lattice
Ryuta Yamamoto, Hideki Ozawa, David C. Nak +2
We demonstrate single-site-resolved fluorescence imaging of ultracold atoms in a triangular optical lattice by employing Raman sideband cooling. Combining a Rama…
