Abstract
In the sodium dimer rhomb-type four-level system with a pair of coherent superposition levels, the interference enhancement of two-photon absorption caused by coherent superposition of the coupling levels is experimentally observed. The calculated results using density matrix equation are in good agreement with the experimental results.
