These results reveal common dynamics of this optically-induced phase transition that are independent of this disorder. Above the fluence threshold for completing the transition to the rutile crystalline phase, we find a common time scale, independent of sample morphology, of 40.5 +/- 2 ps that is consistent with nucleation and growth dynamics of the R phase from the parent M1 ground state.
