Optomechanical cooling
WebWe analyze the performance of optomechanical cooling of a mechanical resonator in the presence of a degenerate optical parametric amplifier within the optomechanical cavity, which squeezes the cavity light. We demonstrate that this allows to significantly enhance the cooling efficiency via the coherent suppression of Stokes scattering. The enhanced … WebA well-established method for doing so is feedback cooling, in which a strong probe field interacting with the cavity optomechanical system is used to measure the mechanical position which is then used to apply a feedback force back onto the mechanical oscillator in order to stop its motion, thereby reducing the mechanical noise (quantified by ...
