Direct Measurement of Coating Thermal Noise Using Cryogenic Optical Cavities
The optical coatings used in gravitational-wave detectors constitute the dominant source of thermal noise. This noise is called coating thermal noise. Coating thermal noise is one of the most important noise sources in gravitational-wave detectors at most sensitive frequency range. To reduce this noise, direct measurement is indispensable. So far, I have performed simulations and developed optical systems for direct measurement. I will report the current status.
