Mechanical quality factor estimation from a nonlinear optical cavity response
Zohran Ali, Davide Tomasella, Daniel Allepuz-Requena +3
Intrinsic damping rate and quality factor () are key parameters in optomechanical systems. However, in high-Q devices, their measurement is often challenging because probe-induc…
High-yield fabrication of micromirror templates via feedback-controlled laser ablation
Daniel Allepuz-Requena, Jonas Schou Neergard-Nielsen, Alexander Huck +1
We present a high-yield method for fabricating concave micromirror templates in silica using feedback-controlled CO2 laser ablation with precise in situ positioning. Real-time moni…
Mitigating nonlinear transduction noise in high-cooperativity cavity optomechanics
Daniel Allepuz-Requena, Zohran Ali, Dennis Høj +4
Coupling mechanical motion to an optical resonator enables displacement measurements approaching the standard quantum limit (SQL). However, increasing the optomechanical coupling s…
High-Speed NV Ensemble Magnetic Field Imaging via Laser Raster Scanning
Luca Troise, Nikolaj W. Hansen, Marvin Holten +4
We present a technique that uses an ensemble of nitrogen-vacancy (NV) centers in diamond to image magnetic fields with high spatio-temporal resolution and sensitivity. A focused la…
