Optical Cavities for Optical Atomic Clocks, Atom Interferometry and Gravitational-Wave Detection

by Miguel Dovale Álvarez

Overview

Devised at the beginning of the 20th century by french physicists Charles Fabry and Alfred Perot, the Fabry-Perot optical cavity is perhaps the most deceptively simple setup in optics, and today a key resource in many areas of science and technology. This thesis delves deeply into the applications of optical cavities in a variety of contexts: from LIGO’s 4-km-long interferometer arms that are allowing us to observe the universe in a new way by measuring gravitational waves, to the atomic clocks used to realise time with unprecedented accuracy which will soon lead to a redefinition of the second, and the matterwave interferometers that are enabling us to test and measure gravity in a new scale. The work presented accounts for the elegance and versatility of this setup, which today underpins much of the progress in the frontier of atomic and gravitational experimental physics.

About the Author

Miguel Dovale Alvarez (Santiago de Compostela, 1989) is a spanish-american physicist and member of the LIGO Scientific Collaboration. He holds a Licenciatura in Physics from Universidade de Santiago de Compostela (Spain), and a PhD from the University of Birmingham (UK). His main research interests are laser interferometry, quantum optics and gravitational physics. During his doctorate he developed a thermal-noise-limited Fabry-Perot interferometer at the National Physical Laboratory (UK). Dovale is now a postdoc at the Max Planck Institut für Gravitationsphysik (Hannover, Germany), where he works in several aspects of the LISA interferometry chain.
