Nanophotonic structures in single--crystal diamond (SCD) that simultaneouslyconfine and co-localize photons and phonons are highly desirable forapplications in quantum information science and optomechanics. Here we describean optimized process for etching SCD microdisk structures designed foroptomechanics applications. This process allows the optical quality factor,$Q$, of these devices to be enhanced by a factor of 4 over previousdemonstrations to $Q \sim 335,000$, which is sufficient to enable sidebandresolved coherent cavity optomechanical experiments. Through analysis ofoptical loss and backscattering rates we find that $Q$ remains limited bysurface imperfections. We also describe a technique for altering microdiskpedestal geometry which could enable reductions in mechanical dissipation.
