| Abstract | of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy LASER NOISE MITIGATION THROUGH TIME DELAY INTERFEROMETRY FOR SPACE-BASED GRAVITATIONAL WAVE INTERFEROMETERS USING THE UF LASER INTERFEROMETRY SIMULATOR By Shawn J. Mitryk May 2012 Chair: Guido Müller Major: Physics The existence of gravitational waves was theorized in 1916 by Albert Einstein in accordance with the linearized theory of general relativity. Most experiments and observations to date have supported general relativity, but now, nearly 100 years later, the scientific community has yet devise a method to directly measure gravitational radiation. With the first attempts towards a gravitational wave measurement in the 1960s, many methods have been proposed and tested since then, all failing thus far to provide a positive detection. The most promising gravitational radiation detection method is through the use of a space-based laser interferometer and with the advancement of modern technologies, these space-based gravitational wave measurements will eventually provide important scientific data to physics, astro-physics, and astronomy communities. The Laser Interferometer Space Antenna (LISA) is one such space-based laser interferometer. LISA’s proposed design objective is to measure gravitational radiation in the frequency range from 30μHz to 1Hz using a modified Michelson interferometer. The interferometer arms are 5Gm in length measured between each of the 3 spacecraft in the interferometer constellation. The differential arm-length will be measured to an accuracy of 18 pm/ √ Hz resulting in a baseline strain sensitivity of 3.6 × 10−21 / √ Hz . Unfortunately, the dynamics of the spacecraft orbits complicate the differential |
