Reducing Thermoelastic Noise in Gravitational-Wave Interferometers by Flattening the Light Beams
Erika D'Ambrosio, Richard O'Shaughnessy, Sergey Strigin +2
In the baseline design for advanced LIGO interferometers, the most serious noise source is tiny, dynamically fluctuating bumps and valleys on the faces of the arm-cavity mirrors, c…

The implications of Mexican-hat mirrors: calculations of thermoelastic noise and interferometer sensitivity to perturbation for the Mexican-hat-mirror proposal for advanced LIGO
R. O'Shaughnessy, S. Strigin, S. Vyatchanin
Thermoelastic noise will be the most significant noise source in advanced-LIGO interferometers with sapphire test masses. The standard plan for advanced-LIGO has optimized the opti…
