Abstract

<p>It has become possible to laser cool mechanical oscillators, i.e., massive macroscopic objects, just like atomic gases and ions in a vacuum. In this article we aim at understanding the way in which Brownian motion of mechanical oscillators can be cooled with a laser and a cavity by simple and phenomenological classical arguments. Equipped with the classical model we present the first photo-thermal-effect-based cavity cooling experiment of a metal-coated cantilever, our cavity cooling experiment with a semiconductor nanomembrane, and radiation-pressure-based cavity cooling experiments.</p>
