In this collection of work, I will first guide the reader toward an understanding of optical tweezers, a technique used to trap small refractive particles, such as glass microspheres or living cells. In 2019, Arthur Ashkin was awarded part of the Nobel Prize in Physics for his development of this technique, and he made many of the initial strides in the field. With a general understanding of optical tweezers, I will discuss the specific setup and implementation constructed in our group at Stanford, especially those aspects that are particularly unique or novel to the apparatus. All of the work presented has been performed with optically trapped silica microspheres in vacuum, using a single-beam trapping technique with interferometric readout. I will then move to a discussion of a number of technical developments with metrological applications including: force field microscopy, direct measurements of a levitated microsphere's mass and radius, control of the microsphere's rotational degrees of freedom, and residual gas sensing.To conclude, I will explore some of the fundamental science goals of the project, including results from searches for fifth forces related to both dark energy and more general modifications to Newtonian gravity that might arise from new physics that manifest in the submillimeter regime.
