Thermorefringent noise in crystalline optical materials
Serhii Kryhin, Evan D. Hall, Vivishek Sudhir
Any material in thermal equilibrium exhibits fundamental thermodynamic fluctuations of its mechanical and optical properties. Such thermodynamic fluctuations of length, elastic con…
Quantum correlation measurements in interferometric gravitational wave detectors
D. V. Martynov, V. V. Frolov, S. Kandhasamy +199
Quantum fluctuations in the phase and amplitude quadratures of light set limitations on the sensitivity of modern optical instruments. The sensitivity of the interferometric gravit…
Coherent Cancellation of Photothermal Noise in GaAs/AlGaAs Bragg Mirrors
Tara Chalermsongsak, Evan D. Hall, Garrett D. Cole +7
Thermal noise is a limiting factor in many high-precision optical experiments. A search is underway for novel optical materials with reduced thermal noise. One such pair of materia…
Broadband Measurement of Coating Thermal Noise in Rigid Fabry-Perot Cavities
Tara Chalermsongsak, Frank Seifert, Evan D. Hall +3
We report on the relative length fluctuation of two fixed-spacer Fabry-Perot cavities with mirrors fabricated from silica/tantala dielectric coatings on fused silica substrates. By…
