Abstract: Levitated optical mechanical systems have demonstrated excellent force and impulse sensitivity and are currently being developed for the creation of non-classical states of motion in these new quantum systems. An important requirement in the design of these systems is the ability to independently control and cool all three translational degrees of freedom. Here, we describe the design and implementation of a stable and robust 3D velocity feedback cooling scheme with particular emphasis on creating minimal crosstalk between the independent oscillatory modes when cooling.
