Optomechanical vector sensing of new forces at 6 micron separation
Gautam Venugopalan, Clarke A. Hardy, Kenneth Kohn +10
The search for new gravity-like interactions at the sub-millimeter scale is a compelling area of research, with important implications for the understanding of classical gravity an…
Platinum Black for stray-light mitigation on high-aspect-ratio micromechanical cantilever
Gautam Venugopalan, Giorgio Gratta
Microscopic devices are widely used in optomechanical experiments at the cutting-edge of precision experimental physics. Such devices often need to have high electrical conductivit…
Librational Feedback Cooling
Charles P. Blakemore, Denzal Martin, Alexander Fieguth +4
Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the c…
Scattering Loss in Precision Metrology due to Mirror Roughness
Yehonathan Drori, Johannes Eichholz, Tega Edo +5
Optical losses degrade the sensitivity of laser interferometric instruments. They reduce the number of signal photons and introduce technical noise associated with diffuse light. I…
Global optimization of multilayer dielectric coatings for precision measurements
Gautam Venugopalan, Francisco Salces-Cárcoba, Koji Arai +1
We describe the design of optimized multilayer dielectric coatings for precision laser interferometry. By setting up an appropriate cost function and then using a global optimizer…
