  • The enhancement of resonant sum-frequency generation through quantum control, which employs the continuum states, was discussed. The scheme employs all-resonant coupling and trade-off optimization of the constructive and destructive quantum interference effects in the higher-order and lower-order polarizations controlled by the overlap of two autoionizinglike laser-induced continuum structure. It was found that the analytical solution of coupled density-matrix equations were implemented for analysis of the solution of Maxwell's equation describing four-wave mixing. The results show that the feasibility of the nearly complete conversion of low-frequency radiation to sum frequency radiation was shown for the case of quasiresonant coupling.
