Figure 5
Dependence of the populations difference \(\rho _{11}-\rho _{22}\) (a), \(\rho _{11}-\rho _{33}\) (b), \(\rho _{22}-\rho _{33}\) (c) on the delay \(\Delta\) between two Gaussian THz pulses and time t for parameters of the \(H_20\) molecule (\(\omega _0/2\pi =0.97\) THz, \(d_{12}=19.2\) Debye). Other parameters: \(E_0= 150\) kV/cm, \(\tau _p=150\) fs, \(T_{22}=T_{33}=250\) ps, \(T_{21}=T_{32}=T_{31}=5\) ps. This figure was created with Matlab R2016b (www.mathworks.com).
