Speed characterization of the nonlinear polarization effect. Dynamic response of the nonlinear polarization effects under green light modulations. The chopped green light (shown by green curves) acts as the trigger reference for an oscilloscope. The red curves show the temporal response of the transmitted signal light, along with the double-exponential fitting curves. The horizontal dashed lines present the background level of the signal light before green light excitation.
