Optomechanical cooling
WebThis was pioneered by Braginsky and co-workers in their work on optomechanical damping [1,2], while the associated cooling effect was first demonstrated only rather recently [7]. The main ingredient for optomechanical cooling is the appearance of extra damping, ideally without extra fluctuations. This damping is introduced because the light-induced WebOct 7, 2024 · The conventional method of laser cooling is limited by the quantum backaction, which requires the mechanical sideband to be resolved in order to cool to …
