Abstract :
We employ silica microspheres to detect and actuate nanomechanical motion. With Si3N4-nanostrings, we achieve significant passive cooling by radiation pressure. Feedback-cooling enables stable operation at optical powers beyond the parametric-instability threshold, paving the way to detect quantum backation.
