a Magnetic-field-dependent CW ODMR at T = 10 K and PMW ≈ 50 mW. ESR fits to Eq. (2) have been marked with blue and red dashed lines, respectively. b CW ODMR spectra at T = 250 K (orange), 100 K (green), and 10 K (blue) at B0 = 450 G and PMW ≈ 2.51 W. c Temperature dependence of the ESR linewidths for both the GS (blue) and ES (red) at PMW ≈ 2.51 W. Error bars represent the standard deviation of the fitted parameter. d Relative contrast of the ES ESR with respect to the GS ESR contrast at PMW ≈ 2.51 W.
