Enhancement of cavity cooling of a micromechanical mirror using parametric interactions

摘要: It is shown that an optical parametric amplifier inside a cavity can considerably improve the cooling of micromechanical mirror by radiation pressure. The be cooled from room temperature $300\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ to sub-Kelvin temperatures, which much lower than what achievable in absence amplifier. This further illustrated case precooled mirror, where one reach millikelvin temperatures starting with about $1\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Our work demonstrates fundamental dependence pressure effects on photon statistics.
