Light narrowing of magnetic resonances in ensembles of nitrogen-vacancy centers in diamond
Light narrowing of magnetic resonances in ensembles of nitrogen-vacancy centers in diamond
We investigate optically detected magnetic resonance signals from an ensemble of nitrogen-vacancy centers in diamond. The signals are measured for different light powers and microwave powers, and the contrast and linewidth of the magnetic-resonance signals are extracted. For a wide range of experimental settings of the microwave and light powers, …
