    Study the Quantum Coherence Induced Transparency of Two Separate Light Beams in Atomic Vapor
    Author(s): Hong Gao

    Quantum coherence has been explored in many interesting phenomena in the past two decades. Quantum coherence occurring in the interaction between light and atoms, can be produced by two orthogonal polarized laser beams coupling with a three-level system. Atoms simultaneously exposed by two overlapping laser beams generate a coherent state, which can make one of these laser beams transmit without any absorption. Coherent population transfer among quantum states of atoms and molecules has also been studied, which is named stimulated Raman adiabatic passage (STIRAP). The procedure of STIRAP relies on the initial creation of a coherence with subsequent adiabatic evolution. Xiao et al. observed this phenomena of atomic coherence production at one position and recovered the coherence at another location. So far, no experiment has shown that the atomic coherence can be generated with two spa.. View More»
