## Description

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