摘要: We investigated the relationship between two- and three-photon coherence in terms of transition routes coupling field intensities a Doppler-broadened ladder-type atomic system for 5S1/2–5P3/2–5D5/2 87Rb atoms. Three-photon electromagnetically induced absorption (TPEIA) due to was observed only route that exhibited dominant two-photon effect. showed is necessary condition phenomena. A comparison relative magnitudes transparency TPEIA as function intensity revealed increase faster than coherence. Considering three-level system, relation numerically calculated.
