Nitrogen-vacancy (NV) centers in diamonds are a powerful tool for accuratemagnetic field measurements. The key is precisely estimating thefield-dependent splitting width of the optically detected magnetic resonance(ODMR) spectra of the NV centers. In this study, we investigate the opticalpower dependence of the ODMR spectra using NV ensemble in nanodiamonds (NDs)and a single-crystal bulk diamond. We find that the splitting widthexponentially decays and is saturated as the optical power increases.Comparison between NDs and a bulk sample shows that while the decay amplitudeis sample-dependent, the optical power at which the decay saturates is almostsample-independent. We propose that this unexpected phenomenon is an intrinsicproperty of the NV center due to non-axisymmetry deformation or impurities. Ourfinding indicates that diamonds with less deformation are advantageous foraccurate magnetic field measurements.
