Angular trapping of a mirror using radiation pressure

<p>Alignment control in gravitational-wave detectors has consistently proven to be a</p> <p>dicult problem due to the stringent noise contamination requirement for the gravitational</p> <p>wave readout and the radiation-pressure induced angular instability in Fabry-</p> <p>Perot cavities (Sidles-Sigg instability). In this thesis, I present optical springs as a</p> <p>tool to damp the motion of a mirror. I discuss the design and implementation of a single</p> <p>degree-of-freedom optical spring system and the importance of the photothermal</p> <p>eect in properly predicting optical spring behavior.</p> <p>I also present the development and implementation of an angular control scheme,</p> <p>attempting to damp two degrees of freedom with two optical cavities. I then extend</p> <p>this understanding into a plausible concept for implementing optical-spring-based</p> <p>angular control in the Advanced LIGO detectors.</p>
