title = "Impact of the laser uniformity on the magnetic sensing with nitrogen-vacancy centers in diamond",
abstract = "Here we theoretically analyzed the impact of the laser uniformity on the magnetic sensitivity with the negatively charged nitrogen-vacancy (NV-) centers in diamond. The maximum slope of the optically detected magnetic resonance signal was simulated under Gaussian laser excitation. The signal to noise ratio (SNR) with different integral radius was calculated. Results show that the SNR can be improved by selectively integrating the fluorescence within the optimal integral radius. The SNR can be improved by 16.4\% under conditions that the average excitation rate is 69.6 kHz and Rabi frequency is 250 kHz. This method will benefit the sensitivity improvement of NV-based sensors with CCD detection.",
