Controlling the dynamics of mechanical resonators is central to many quantum\nscience and metrology applications. Optomechanical control of diamond\nresonators is attractive owing to diamondās excellent physical properties and\nits ability to host electronic spins that can be coherently coupled to\nmechanical motion. Using a confocal microscope, we demonstrate tunable\namplification and damping of a diamond nanomechanical resonatorās motion.\nObservation of both normal mode cooling from room temperature to 80K, and\namplification into selfāoscillations with $60\,\mu\text{W}$ of optical power\nis observed via waveguide optomechanical readout. This system is promising for\nquantum spin-optomechanics, as it is predicted to enable optical control of\nstress-spin coupling with rates of $\sim$ 1 MHz (100 THz) to ground (excited)\nstates of diamond nitrogen vacancy centers.\n
