Abstract

Many plans for future gravitational wave detectors have ensued the ground-breaking gravitational wave events detected here on earth since September 2015. The extent of the accessible universe of both future and current detectors critically depends on improved instrumentation. This thesis investigates the novel Double End-Mirror Sloshing or "OEMS" cavity design to meet stringent low-noise requirements for creating a "white-light -cavity" interferometer which will be more sensitive to a variety of extra-terrestrial signals. Theory and experiments are undertaken that demonstrate that the OEMS cavity will introduce minimal radiation pressure heating to mechanical resonators and enable ultra-low thermal bath coupling.
