Light slowing and all-optical time division multiplexing of hybrid four-wave mixing signal in nitrogen-vacancy center |
(a) Hybrid signal under the illumination of 637-nm pulse laser in time domain. The red and blue lines in both figures are fitting curves. The graph at the top right corner (inset) is the zoom-in of the left peak at gated integrator range set from 0 μs to 2 μs. (b) The value log I(t) measured at peak B. (c) The Rabi oscillations of peak A for Stokes and anti-Stokes beams. (d) Two FWM generation channels in the two-level system. |
