A new method for two-beam coupling measurements based on acousto-optic modulation with subhertz tuning capability is applied to study excited-state dynamics of the nitrogen-vacancy center in diamond. Results yield fundamental decay constants and the nonlinear refractive index and are in good agreement with the calculated dual grating response to resonances in the microscopic susceptibility due to intersystem crossing and spin-lattice relaxation.
