Broadband Thermal Noise Correlations Induced by Measurement Back-Action
Jiaxing Ma, Thomas J. Clark, Vincent Dumont +1
Modern mechanical sensors increasingly measure motion with precision sufficient to resolve the fundamental thermal noise floor over a broad band. Compared to traditional sensors --…

Detuning-symmetric laser cooling of many mechanical modes with a photothermally modified cavity
Thomas J. Clark, Jiaxing Ma, Jack C. Sankey
We simultaneously cool 100 mechanical modes of a membrane with a photothermally modified optical cavity driven by a single blue-detuned laser. In contrast to radiation pre…

Monitored wet-etch removal of individual dielectric layers from high-finesse Bragg mirrors
Simon Bernard, Thomas J. Clark, Vincent Dumont +2
It is prohibitively expensive to deposit customized dielectric coatings on individual optics. One solution is to batch-coat many optics with extra dielectric layers, then remove la…
