Query: Optimization of the power broadening in optically detected magnetic
  resonance of defect spins in silicon carbide   Defect spins in silicon carbide have become promising platforms with respect
to quantum information processing and quantum sensing. Indeed, the optically
detected magnetic resonance (ODMR) of defect spins is the cornerstone of the
applications. In this work, we systematically investigate the contrast and
linewidth of laser-and microwave power-dependent ODMR with respect to
ensemble-divacancy spins in silicon carbide at room temperature. The results
suggest that magnetic field sensing sensitivity can be improved by a factor of
10 for the optimized laser and microwave power range. The experiment will be
useful for the applications of silicon carbide defects in quantum information
processing and ODMR-dependent quantum sensing.
