| 摘 要： | Quantum interference may lead to suppression and enhancement of the two-photon resonant nondegenerate fourwave mixing signal in a cascade four-level system.Such phenomena are demonstrated in Ba through inducing atomic coherence between the ground state 6s^2 and the doubly excited autoionizing Rydberg state 6trod.This method can be used as a new spectroscopic tool for measuring the transition dipole moment between two highly excited atomic states.
